Part one explained the physics of quantum computing. This piece explains the target — how bitcoin's encryption works, why a ...

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 ...

This week, Google published a paper describing how a quantum computer could theoretically derive a bitcoin private key in 9 minutes, with ramifications that stretch to Ethereum, other tokens, private ...

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 ...

Optical quantum computers are gaining attention as a next-generation computing technology with high speed and scalability. However, accurately characterizing complex optical processes, where multiple ...

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...

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: ...

The idea behind quantum computing has existed for a long while now, with the primary goal being to basically create supercomputers capable of calculating intensive problems almost instantly. While we ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

The latest "Google Doodle" to adorn the Google search engine home page is celebrating achievements in quantum physics - and aiming to spread interest in the field. Google's Doodle webpage explains ...
