King’s College team wins access to cutting‑edge Google quantum chip

Scientists from King’s College London have become the first UK academic research team to gain access to Google’s cutting‑edge quantum computer chip Willow as part of a scheme launched with the UK’s national quantum lab last year.

What Willow can do

Google says Willow can solve a theoretical problem in five minutes that would take the world’s current fastest supercomputers 10 septillion (10 000 000 000 000 000 000 000 000) years to complete. The chip’s capabilities stem from quantum mechanics—the science that explains how physical particles behave—and make quantum computers far better suited to certain tasks than classical machines.

Researchers’ perspective

King’s lead for the project, Dr Eleanor Crane, explained that using Willow would “light a torch” for research into the most important natural processes.

“It would be useful if society could understand how plants transform sunlight into energy, find materials which transport electricity quickly, or how molecules bind to each other,” she said. Dr Crane will co‑lead the team alongside Dr Alexander Schuckert from ENS Paris.
“If we could get to grips with these processes, then we could use this understanding to create better solar cells, more efficient energy‑grid systems, and discover drugs for previously untreatable diseases,” Crane added.

Research goals

The King’s team will develop techniques that enable a quantum computer to model natural systems—such as photosynthesis—and answer fundamental questions about them.

Wider quantum landscape

• Google Quantum chief operating officer Charina Chou praised King’s “compelling research proposal”.
• NQCC Director Dr Michael Cuthbert highlighted the initiative as evidence of the UK’s commitment to world‑class quantum research.
• Cambridge University recently announced its largest corporate partnership with American quantum‑tech firm IonQ, aiming to host what it claims will be the UK’s most powerful quantum computer.
• Google faces strong competition from rivals such as IBM, which have solid track records in quantum research.

Future considerations

Quantum computers will not replace classical machines; many tasks remain better suited to conventional computers. However, if the technology lives up to expectations, it could provide solutions to problems that are currently intractable.

There are also security concerns. As quantum machines become more powerful, they may eventually break the encryption that protects everything from cryptocurrency transactions to private messages. Some tech and finance companies have already begun steps to protect their systems from future quantum‑powered threats.
