The Royal Swedish Academy of Sciences has awarded Google’s Chief Scientist of Quantum Hardware the Nobel Prize in Physics alongside former Google employee John Martinis, and University of California, Berkeley professor John Clarke. This is the second year in a row that current or former Google employees have been awarded the prestigious prize: In 2024, a former Google vice president was awarded the Nobel Prize in Physics and the Nobel Prize in Chemistry was shared by researchers from Google DeepMind.
This year’s Nobel Prize in Physics is being awarded in recognition of “the discovery of macroscopic quantum mechanical tunnelling and energy quantization in an electric circuit.” Google puts it more plainly in its blog, writing that Devoret, Martinis and Clarke “created a superconducting electrical circuit” with a feature called a Josephson Junction “that can be used to create and manipulate… quantum phenomena.”
Google says the group’s experiments with Josephson Junctions in 1984 and 1985 were important, not just for the field of physics, but also its current research into quantum computing. The work of the company’s Quantum AI team is occasionally trotted out as a glimpse of a future where major scientific discoveries are driven by hyperefficient computers. See, for example, the Willow quantum chip the company announced last year. Google is ultimately still working on creating the fundamental components that will power these computers, though. And “Josephson Junctions form the basis for today’s superconducting quantum bits (qubits),” an enabler of many of the quantum computing milestones it’s hit in the last few years.
“It is wonderful to be able to celebrate the way that century-old quantum mechanics continually offers new surprises,” Olle Eriksson, Chair of the Nobel Committee for Physics, shared in a press release announcing the winners. “It is also enormously useful, as quantum mechanics is the foundation of all digital technology.”
