Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Quantum computers still face limits when it comes to storing information. Researchers at ETH Zurich are now turning to ...

This article is part of a package on the future of quantum computing. Read about the quest to develop these machines here and see an illustrated field guide to qubits here. The 21st-century fervor ...

Quantum computers have the potential to transform science, accelerating breakthroughs in drug development, cosmology, materials science, nuclear physics, and more. To make this future a reality, ...

A quantum computer has accurately reproduced real experimental data on an unprecedented scale. Classical computers are faster and more accurate than the quantum variety. Even so, the simulation ...

Quantum computing has long felt like a perpetual promise — a mysteriously powerful technology that’s always “about 10 years away.” If you tuned it out, you weren’t alone. But something has shifted ...

Quantum computing seems to pop up in the news pretty often these days. You’ve probably seen quantum chips gracing your feeds and their odd, steampunk-ish cooling systems in the pages of magazines and ...

While the billion-dollar question is about when quantum computing will become commercially viable, one of the problems being tackled at the moment is how to make the ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

John Martinis is a hardware guy. He prefers the nitty-gritty of doing physics in the lab over the idealised world of textbooks. But you couldn’t write the quantum computing history books without him: ...

Google has published research suggesting a future quantum computer could theoretically derive a bitcoin private key from its public key in about nine minutes, threatening the security of Bitcoin and ...
