Director of Quantum Computing Julie Love: Microsoft making progress on quantum computer ‘every day’

Microsoft is “all-in” on building a quantum computer and is making advancements “every day”, according to one of the company’s top experts on the technology.

Julie Love (above), Director of Quantum Computing, called the firm’s push to build the next generation of computer technology “one of the biggest disruptive bets we have made as a company”.

Quantum computing has the potential to help humans tackle some of the world’s biggest problems in areas such as materials science, chemistry, genetics, medicine and the environment. It uses the physics of qubits to create a way of computing that can work on specific kinds of problems that are impossible with today’s computers. In theory, a problem that would take today’s machines billions of years to solve could be completed by a quantum computer in minutes, hours or days.



While Microsoft has noted that no one has yet built a working quantum computer, Love said the company has the right team in place to make progress and eventually create a system and software that can tackle real-world issues. Over the past decade, Microsoft has built a team comprised of some of the greatest minds in quantum physics, mathematics, computer science and engineering. It is also working with some of the leading experts in universities across the world.

“Quantum computers could solve a set of problems that are completely intractable to humans at this time, and it could do so in 100 seconds,” she said during a speech at London Tech Week. “Microsoft’s enterprise customers are interested in changing their businesses using this technology, and we have set our sights beyond the hype cycle. We have a good understanding of what’s needed.

“Microsoft is working on the only scalable solution, one that will run seamlessly on the Azure cloud, and be much more immune to errors. The truth is that not all qubits are equal; most are inherently unstable and susceptible to error-creating noise from the environment. Our approach uses topological qubits specifically for their higher accuracy, lower cost and ability to perform long enough to solve complex real-world problems.”

Microsoft is the only major company attempting to build topological qubits, which aims to significantly reduce any interference at a subatomic level that might affect the machine. With this approach, the computational qubits will be “corrected” by the other qubits.



“When we run systems, there are trade-offs in power, because they have to be very cold. However, we get higher compute capabilities,” said Love, who started studying quantum computing in the late-1990s.

Last year, Microsoft released a Quantum Development Kit, which includes its Q# programming language for people who want to start writing applications for a quantum computer. These can be tested in Microsoft’s online simulator. Q# is designed for developers who are keen to learn how to program on these machines whether or not they are experts in the field of quantum physics.

“We have released the Quantum Development Kit so developers can learn to program a quantum computer and join us on this journey,” Love added.
