Microsoft scientist Dr. Matthias Troyer accepts Hamburg Prize for Theoretical Physics for quantum contributions

This week, Dr. Matthias Troyer, a Distinguished Scientist at Microsoft, accepted the 2019 Hamburg Prize for Theoretical Physics – one of the most valuable German prizes in the field – for his groundbreaking contributions to the development of quantum Monte Carlo algorithms.

“In Professor Troyer, we are honoring a scientist whose work connects myriad areas of physics and computer science. On account of his current research in the field of quantum computing, he partners with universities and companies in the US and around the world. He has also set up an open-source platform in order to share his knowledge. By awarding the prize to Professor Troyer, we also wish to recognize this contribution to collaborative research,” explained Dr. Nina Lemmens, Member of the Executive Board of the Joachim Herz Stiftung.

Dr. Troyer works at the interface between computer science and theoretical physics and is one of just a handful of leading international researchers in this field. Monte Carlo algorithms can predict how tiny particles will interact within quantum mechanical many-body systems such as atoms and molecules, and Dr. Troyer’s work in this area is playing a key role in the research and ongoing development of quantum computers and superconducting materials.

When asked about what this honor means to him, Dr. Troyer said, “One reason I came to Microsoft and why I want to build a quantum computer is that when inventing these Monte Carlo methods, we made big breakthroughs, but we also encountered a fundamental problem of Monte Carlo simulations of quantum systems, the so-called  ‘sign problem.’ The workaround becomes exponentially difficult; a quantum computer will help us move past these barriers.”

With the recent Microsoft announcement of Azure Quantum, teams will soon be able to experiment running algorithms like Monte Carlo against both classical hardware in Azure and quantum hardware from partners, knowing these solutions will scale to future quantum systems as well.

The prize not only comes with a grant, but also entails research visits to Hamburg that will see Dr. Troyer give talks and work closely with doctoral candidates, postdocs, and other colleagues.

Dr. Troyer continued, “I’m looking forward to engaging the academic community in discussing and further advancing what we can do with quantum computing. As we think of quantum algorithms for material science, what problems can we solve now with quantum simulations? And how do we develop quantum algorithms to run once we have a fully scalable quantum computer?”

“The connection to Hamburg means that we can engage with the academic and scientific communities, and with that, I look forward to talking to the people in Hamburg – and around the world – about applying quantum systems and quantum computing to make an impact on material science problems.”

Microsoft and the Azure Quantum team congratulate Dr. Troyer on this significant recognition, and we look forward to supporting his important work in making an impact in solving some of the world’s toughest challenges with quantum computing.

Introducing Azure Quantum: our next step in delivering quantum impact

At Microsoft Quantum, our ambition is to help solve some of the world’s most complex challenges through the world’s most scalable quantum system.

To deliver on that promise, we’ve been working together with a global quantum community to innovate across every layer of the quantum stack – from applications and software down to control and devices.

  • Leading cryptographers at Microsoft Research are developing quantum-resistant public-key cryptographic algorithms and protocols to prepare customers and data centers around the world for a quantum future.
  • Developers are already contributing to the growing quantum community through Q# and our open source Quantum Development Kit, which today has more than 200,000 downloads.
  • Recently, Microsoft’s Quantum Lab located at the University of Sydney made breakthroughs in qubit control technology that allow us to scale beyond the physical limitations of current conventional systems. We now have the ability to control up to 50,000 qubits through simply three wires, a cryogenic CMOS design, and a 1cm2 chip computing at near absolute zero temperatures.

Delivering quantum impact today

Customers across a wide range of industries are already seeing the impact of our quantum solutions built on the tools and services available in Azure.

In collaboration with Microsoft, Case Western Reserve University created an MRI scan that takes a third of the time of a conventional MRI based on quantum solutions running on classical hardware. These advances in speed could help doctors detect diseases earlier, develop new drugs for conditions where progress is hard to measure today, or use imaging to diagnose cancers rather than relying on invasive procedures like biopsies.

OTI Lumionics develops advanced materials for OLED displays for use in next generation consumer electronics. This includes fully transparent displays that can integrate under-display cameras. Using their quantum chemistry applications with Microsoft’s quantum-inspired algorithms running in Azure, the team was able to successfully simulate Alq3, an OLED fluorescent material, with greater accuracy than typical methods available today. These quantum solutions enabled the team to achieve simulation without the need for expensive high-performance computations or a scalable quantum system. This marks a milestone in chemistry simulation that could inspire more efficient and scalable methods of materials, chemical and drug discovery across the industry.

Recently, Microsoft partnered with 1QBit and IonQ to demonstrate end-to-end quantum computing in Azure Quantum. The team collaborated with Dow and identified a problem in which the molecular energy of a ring of hydrogen atoms had to be evaluated. Using 1QBit’s problem decomposition solution expressed in Q#, the team was able to run computation in Azure against IonQ’s quantum computer based on trapped ions. This demonstrates how Azure Quantum can start to fuel innovations across the quantum stack – from applications and algorithms down to simulators and hardware. By bringing these end-to-end capabilities into one platform, the quantum community will be able to unlock new solutions that scale to even greater impact in the future.

Microsoft, Brilliant team up to offer quantum curriculum

With the Microsoft Quantum Development Kit, getting started with quantum development is easy. Now we’re helping to make it even easier: we’ve partnered with the team of educators at to teach you about quantum computing in a new way.

Brilliant has more than 8 million students and professionals worldwide learning subjects from algebra to special relativity through guided problem-solving. In partnership with Microsoft’s quantum team, Brilliant has launched an interactive course called “Quantum Computing,” for learning quantum computing and programming in Q#, Microsoft’s new quantum-tuned programming language. The course features Q# programming exercises with Python as the host language (one of our new features!). Brilliant and Microsoft are excited to empower the next generation of quantum computer scientists and engineers and start growing a quantum workforce today.

Starting from scratch

Because quantum computing bridges the fields of information theory, physics, mathematics, and computer science, it can be difficult to know where to begin. Brilliant’s course, integrated with some of Microsoft’s leading quantum development tools, provides self-learners with the tools they need to master quantum computing.

The new quantum computing course starts from scratch and brings students along in a way that suits their schedule and skills. Students can build and simulate simple quantum algorithms on the go or implement advanced quantum algorithms in Q# on the web, without ever downloading a development environment.

Basic q sharp courseBasic q sharp course

From quantum Plinko to teleportation and algorithms

Quantum Computing covers quantum information, quantum operations, and introductory algorithm design in an intuitive way. Quantum Computing, the fundamental concepts of quantum information are built up from first principles, and then by finding and addressing the points where classical intuition falls apart. The course aims to present the deep mysteries of quantum phenomena in an approachable way. For example, the course begins with a ball bouncing down The Price is Right®’s Plinko board and then—with a few added lasers—reveals an example of boson sampling, a simple problem that is likely to be impossible to solve efficiently with a classical computer.

Q# for developing quantum solutions

To teach basic quantum operations, the course features a drag-and-drop simulator that follows the student throughout the course and offloads mathematical heavy lifting so it’s easier to focus on the quantum learnings. Brilliant’s circuit simulator allows self-learners to solve quantum circuit puzzles, peek inside the quantum state at any point along the simulation, and get a feel for the operations that a quantum computer may be able to perform. Such experimentation with full knowledge of a quantum state is a great way to learn the tools of the trade, but to really program a quantum computer, you need to follow quantum rules where observing the quantum state can destroy it. That’s where Microsoft’s Q# programming language comes in. Brilliant incorporates the Q# language into Quantum Computing so that programmers can modify and construct quantum algorithms.

Q# also provides a powerful way to quickly prototype quantum programs in tandem with a classical programming environment. Using Q#’s new Python integration within the Brilliant course, students call Python to implement the classical side of an algorithm and call Q# to run the quantum side—all in a single coding environment in their browser. Q#’s integration with Python provides a glimpse into the future of quantum computing: a classical computer that can leverage quantum hardware for particular problems, in much the same way that we currently use GPUs to speed up the solutions of ray tracing or machine learning problems.

Advanced topics of quantum computing

Even before quantum systems will be sufficient to implement the most well-known algorithms at a useful scale, there may be algorithms that can take advantage of mixed classical and quantum computing. By the end of this course, students will appreciate how a difficult classical problem can be translated into a quantum representation, and experiment with the reality of quantum computation. Quantum Computing also illustrates how quantum hardware may enable large-scale quantum chemistry simulation, by taking learners through the efficient preparation and manipulation of highly-entangled states which are prohibitively costly with classical computers.

Microsoft Quantum collaborates with Willis Towers Watson to transform risk-management solutions

Screen with stylusScreen with stylus

Willis Towers Watson (NASDAQ: WLTW)—a leading global advisory, broking, and solutions company—has long used complex mathematical models to deliver great results for clients and turn risk into growth. However, some problems are still so challenging that they remain intractable with even the most advanced contemporary computational solutions.

Because of that, Willis Towers Watson has joined the Microsoft Quantum Network to partner with Microsoft to explore the ways that quantum-inspired algorithms might assist the firm with its work in the areas of risk management, financial services, and investing.  Quantum-inspired algorithms harness the power of quantum physics to solve hard computational problems in new ways. Using these techniques, Microsoft is already able to gain orders of magnitude of performance acceleration in Azure.  Once quantum computers become available at scale, even greater acceleration is possible.

“Current modelling techniques to quantify risk require a huge amount of computing power, using thousands of computers over many hours,” says Willis Towers Watson CEO John Haley. “Quantum computing offers us the chance to look at our clients’ problems in a different way. By focusing on how we would model the problems on quantum computers when they become available at scale, we are able to work with Microsoft to redefine the problems and speed up our solutions on existing hardware.”

Engaging with our expertise in quantum computing is a natural extension of Willis Towers Watson’s long partnership with Microsoft. It already has improved business agility and productivity with the help of Microsoft’s Office 365 and developed a specialized insurance model on Azure.

“Willis Towers Watson’s ability to apply technology in novel ways to benefit their customers is always inspiring,” said Peggy Johnson, Executive Vice President of Business Development for Microsoft. “We’re thrilled to have our Microsoft Quantum team working side-by-side with their experts to develop next generation modelling tools.”

This sentiment was shared by Haley, who noted: “We are excited to work with Microsoft—they have an incredible amount of brainpower and are on the forefront of quantum computing.”

The addition of Willis Towers Watson to the Microsoft Quantum Network is the latest example of Microsoft working with world-class institutions to apply the techniques of quantum computing to real-world problems. For instance, we have partnered with Case Western Reserve University (CWRU) to show how the power of quantum computing could enhance Case Western’s approach to detecting cancerous tumors. By using a quantum-inspired algorithm that runs on today’s classical computers, Case Western researchers are working to improve the diagnostic capability of magnetic-resonance imaging devices, a key tool used for detecting and fighting cancer.

We’re also working with the Dubai Electricity and Water Authority (DEWA) on developing new quantum-based solutions to address energy optimization and other challenges where classical computers have serious limitations.

Microsoft is pioneering the emerging quantum era through an approach that will deliver the industry’s most stable and scalable quantum computer. As the development of the quantum computer progresses, select partners such as Willis Towers Watson can access new quantum-inspired Azure services through membership in the Microsoft Quantum Network for the most complete, end-to-end quantum programming.

While there is still much work to be done, Willis Towers Watson and Microsoft are excited to see just how quantum-inspired solutions will help transform the way financial industries improve risk management.

New self-paced learning tools make quantum programming more approachable

With the most recent Quantum Development Kit release, we’ve focused on empowering our users to get engaged with quantum development. The new release: 

  • Makes it easier to learn quantum computing with the quantum katas notebooks. 
  • Adds more consistent and concise Q# syntax. 
  • Refactors to focus on helping users find what they want and contribute their code. 

Building upon the Jupyter Notebook integration that we shared with you last month, we now extend the support to our quantum katas – self-paced tutorials on quantum computing. Today’s update means that new Q# developers can experience our self-paced learning tools without having to install the Quantum Development Kit. With this update, we’ve made quantum programming approachable for people with any level of experience.

Quantum katas in jupyter notebookQuantum katas in jupyter notebook

You can try out the kata notebook yourself hosted online, or you can also find a list of other kata notebooks for you to try at our open source Quantum Katas repository.   

Q# makes it easy to think in terms of quantum algorithms and quantum applications. As we continue to evolve the world’s first high-level quantum programming language to meet the needs of scalable quantum program development, we’re also taking the opportunity to make it even easier to express quantum algorithms in Q#.   

With this release, we are adding new capabilities to the Q# language itself.  For example, we added an operator “w/”, a new way to express array creation as a modification of an existing array.  We have also added a shorthand way to express specializations of quantum operations (e.g.: Controlled and Adjoint) and new shorthand, (e.g.:, “w/=, +=)  for common statements. These changes not only improve the developer’s ability to express quantum algorithms, but they will also lead to more efficient code generation on quantum devices. 

Visual Studio and Visual Studio code users will also now see the familiar light bulb icon that recommends fixes for build problems.   

jupyster lightbulb in quantum katasjupyster lightbulb in quantum katas

We have optimized the layout of our libraries to enable the exciting growth that we are seeing from our team and the larger quantum community. As more developers contribute their ideas and Q# code, the new layout helps developers learn and re-use code faster. Learn about these and other new features in the Quantum Development Kit update release notes.

Finally, please take a look at our developer blog this week as we publish a series of more in-depth blogs about each of these new capabilities.

Newly formed Northwest Quantum Nexus aims to accelerate quantum information science

The Northwest is brimming with talented, dedicated people who can deliver quantum computing advances today and secure our quantum future for tomorrow. Today, at the inaugural Northwest Quantum Nexus Summit, we announced the Northwest Quantum Nexus, a coalition assembled by three keystone partners: Microsoft Quantum, the Pacific Northwest National Laboratory, and the University of Washington.

In line with the goals of the National Quantum Initiative Act, the Northwest Quantum Nexus accelerates Quantum Information Science (QIS) to develop a quantum economy and workforce in the greater Pacific Northwest region of the United States and Canada. The high concentration of quantum activity in the Northwest makes it one of the top regions globally to address key QIS needs. The goal of the two-day Summit this week is to bring together the region’s experts who can define the region’s potential to drive quantum computing’s future.

Its objectives include:

  • Bringing together academia, government, startups, and industry to pursue multi-disciplinary QIS research to deliver scalable quantum computing.
  • Pursuing quantum computing via collaborative research and development, targeted quantum algorithms and programming, and the development of quantum materials.
  • Capitalizing on public-private partnerships to promote a rapid exchange of knowledge and resources and drive discoveries in quantum technologies.
  • Applying research outcomes to application areas and testbeds, including clean energy and sustainability.
  • Cultivating the future quantum workforce through programs that range from early to higher education and professional levels, as well as the corresponding network of institutions and outlets offering curriculum and training opportunities.

“The Northwest Quantum Nexus represents another big step toward the development of scalable, stable quantum computers,” says Todd Holmdahl, Corporate Vice President of Microsoft Quantum. “The partnership just makes a lot of sense – we’re already one of the top regions in the world for quantum research, and the Nexus will help us leverage that expertise to build a quantum-ready workforce and boost the region and nation’s quantum ecosystem.”

The Northwest Quantum Nexus intersects with another complementary, broad-based initiative led by Microsoft, the Microsoft Quantum Network. Both the Northwest Quantum Nexus and the Microsoft Quantum Network were begun with the understanding that creating a scalable quantum computer will require the collective effort of many skilled and diverse teams. Just last week, Microsoft hosted the Microsoft Quantum Network’s first Startup Summit.

Creating a regional quantum powerhouse

The Northwest Quantum Nexus partnership unites considerable intellectual talent. The University of Washington is one of the top research institutions in the world. It recently established UW Quantum X, which joins existing research endeavors across the university in QIS, including quantum sensing, quantum computing, quantum communication, and quantum materials.

Recently, in a partnership of Microsoft Quantum researchers and the University of Washington faculty, we identified opportunities to ready students with quantum computing programming skills and an understanding of quantum algorithms. Microsoft researchers now teach quantum computing programming and algorithm development with the Q# programming language, giving students a head start in developing quantum solutions.

Pacific Northwest National Laboratory’s (PNNL) QIS program includes capabilities in algorithm development and programming, as well as expertise in materials synthesis and characterization, quantum chemistry applications, quantum sensing, and workforce development – all fields are seeing tremendous advances today due to the power of a quantum computer.

Microsoft has recently collaborated with PNNL on the Microsoft Quantum Development Kit chemistry library. The library can be used in conjunction with NWChem, an open-source, high-performance computational chemistry tool funded by the U.S. Department of Energy’s Office of Science.   With the state-of-the-art tools provided in the Quantum Development Kit – including resource estimation, algorithm programming, debugging and simulation – this collaboration enables chemists to develop quantum chemistry solutions for a quantum computer, and better understand what that solution can look like today.

As for Microsoft, we’ve been driving advances in quantum computing and software development for 15 years. We see the power of quantum computing as solving some of the world’s most challenging problems for a wide range of industries – healthcare, environmental sciences, financial services, auto engineering, and others. Our team of experts in quantum physics, mathematics, computer science, and engineering have partnered with universities, industry, and government on cross-cutting research to advance our scalable qubit approach across the globe.

Researcher working on quantum hardware

The prominence of the Northwest Quantum Nexus is expected to increase the visibility of QIS research, leading to even greater collaboration and drawing quantum talent – trainees and employers – to the U.S. Locally, the Northwest Quantum Nexus will help position the greater Pacific Northwest region as a global leader for creating and sustaining an exceptional quantum workforce and economy.

Says Krysta Svore, General Manager for Quantum Software at Microsoft: “The Northwest Quantum Nexus is a pivotal element to making scalable quantum computing a reality. It enables the type of synergistic research and development needed to deliver critical technological advances from quantum algorithms and programming to materials design and development.”

Simulating nature with the new Microsoft Quantum Development Kit chemistry library

Quantum computers have the potential to solve the world’s hardest computational problems and alter the economic, industrial, academic, and societal landscape. In just hours or days, a quantum computer can solve complex problems that would otherwise take billions of years to solve.

To unlock these potential applications, the Microsoft Quantum Development Kit includes a new chemistry library that allows chemists to simulate molecular interactions and explore quantum algorithms for real-world applications in the chemistry domain. Features included in the library are state-of-the-art Q# implementations of methods for Hamiltonian simulation – including Trotterization and Qubitization techniques – state preparation techniques, and samples to help chemists to get started quickly.

For example, the 100-year-old Haber-Bosch process, a key industrial process to create artificial fertilizers, might be improved using computational chemistry methods that are enhanced by quantum computing. That could improve the catalytic process for creating ammonia from atmospheric nitrogen, a process that currently requires high temperatures, high pressures, and carefully selected catalysts. This process is so heat- and pressure-intensive that it consumes upwards of two percent of the world’s natural energy sources. Using quantum algorithms such as those supported by the Microsoft Quantum chemistry library, scientists can learn from nature’s natural process of nitrogen fixation how to achieve this task at lower pressures and temperatures.

Microsoft Quantum & Pacific Northwest Laboratory collaboration

The Microsoft Quantum Development Kit chemistry library was developed in collaboration with Pacific Northwest National Laboratory (PNNL), a leader in both chemistry and data analytics. The chemistry library – working with PNNL’s NWChem, an open-source, high-performance computational chemistry tool developed by the U.S. Department of Energy’s Office of Science – enables quantum solutions to solve computationally complex chemistry problems.

Watch this video made with Pacific Northwest National Laboratory:

“Quantum computing has the potential to help us answer our questions much, much faster with much higher accuracy.”  Wendy Shaw, Director, Physical Sciences Division, Pacific Northwest National Laboratory

Tackling hard computational chemistry problems using the quantum chemistry library

To get started in quantum chemistry simulations, the chemistry library offers features such as:

  • State-of-the-art Hamiltonian simulation methods: Two main methods are supported, Trotterization and Qubitization.
    • Trotterization uses the fact that fast alternation of time-slices converges to the given Hamiltonian. This typically leads to quantum circuits that implement the time evolution with a low number of qubits by cycling through all terms that are present in the given Hamiltonian in a sequential way and in a prescribed order.
    • Qubitization is a technique that allows to perform an estimation of energies by way of implementing a linear combination of operators. This typically has a slightly higher cost in terms of qubits compared to Trotterization but can lead to substantially lower circuit size and circuit depth, depending on the chemistry problem at hand. A crucial part of Qubitization quantum algorithms are state-preparation techniques, which are provided as part of this release.
  • Estimation of ground and excited state energies. The chemistry library enables the estimates of ground state and excited state energies as a function of bond distance. Many real-world chemistry problems involve not only estimates of ground state energies but also the understanding of the dynamics of the various transitions between excited states and a characterization of their energy levels. This type of problems can be studied with the new chemistry library as well.

As an example, the figure below shows the results of one of the samples that uses the data from NWChem. It graphically shows the equilibrium bonding distance of Lithium Hydride for various distances and energy levels.

Estimating the ground and excited state energies for equilibrium bonding distance of Lithium Hydride, an inorganic compound with chemical formula LiH.
  • Automatic resource estimation. The Trace simulator that is part of the Quantum Development Kit allows chemists to estimate important metrics about quantum algorithms, such as the number of qubits, the total gate count for various types of primitive gates, and the total circuit depth. Shown below is the output of the GetGateCount sample that is shipped with the library and which computes a variety of useful metrics for various molecular benchmarks that are provided as part of the library.

  • Interface to powerful chemistry modeling tools. The release introduces an open source YAML-based schema called Broombridge (in reference to a landmark celebrated as a birthplace of Hamiltonians), to make it easy for a chemist to input real-world chemistry models into Q#. Broombridge is a structured, extensible, and human-readable and human-editable way of representing electronic structure problems.  Learn more about the schema.
  • Samples: The chemistry library contains several benchmark samples molecules using the to help programmers and chemist simulate molecules and chemical interactions. Some examples:
    • Beta-Carotine: this is a benchmark to study the most common form of carotene in plants and oxidative damage; an ideal candidate for singlet fission processes.
    • C20: this benchmark studies C20 systems often used to calibrate various electron correlation effects.
    • Ozone: this benchmark to study quantum mechanical excited-state studies of the Ozone and an understanding its role in Earth atmosphere.
  • Real-world chemistry modeling in NWChem. The chemistry library interfaces with NWChem, a high-performance computational chemistry software package. There are several ways to explore the interplay between NWChem and the Q# quantum chemistry library, including:
    • Try out the sample molecules listed above that have been generated by NWChem and are already a part of the Quantum Development Kit Samples.
    • Use EMSL Arrows Builder for the Microsoft Quantum Development Kit – a web-based frontend to NWChem – to generate new Broombridge-formatted molecular input files
    • Use the Docker image, provided by PNNL to run NWChem and generate your own molecule models

You can learn more about the chemistry library by exploring the documentation, including a set of conceptual documentation to describe basic principles of quantum chemistry, its mapping to a quantum computer, and the API documentation.

Today, developers and chemists around the world can begin exploring the Microsoft Quantum Development Kit and experiencing the world of quantum computing.  Resources such as the chemistry library will enable problem-solvers in the computational chemistry domain to explore the world of quantum. We’re excited to help our growing community take another step toward the new world of quantum computing.

These processes could break down pollutants in exhaust streams, extract atmospheric nitrogen to make fertilizer, and enable new methods for carbon capture. For example, a quantum computer may help identify a way to remove carbon from our environment more efficiently, to combat global warming.

To unlock these potential applications, this release of the Quantum Development Kit now includes a state-of-the-art chemistry library that allows users to explore quantum algorithms for real-world applications in the computational chemistry domain. New features include:

  • State-of-the-art Q# implementations of methods for Hamiltonian simulation.
  • Various samples to help the user get started quickly.
  • Integrations with NWChem, an open source high-performance computational chemistry software package.

The chemistry library was developed in collaboration with Pacific Northwest National Laboratory (PNNL), a leader in both chemistry and data analytics. Together, the chemistry library and NWChem enable quantum solutions and allow researchers and developers a higher-level of study and discovery as they tackle today’s computationally complex chemistry problems.
