Quantum computers could soon be able to solve genuinely useful mathematical problems faster than classical computers, claims quantum computing firm Quantinuum. It would be the first example of these ...

Two research groups say they have significantly reduced the amount of qubits and time required to crack common online ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...

When a guitar string is plucked or a playground swing is set in motion, the movement gradually fades away. Physicists call these “damped harmonic oscillators,” and Newton’s laws do a fine job of ...

At the forefront of discovery, where cutting-edge scientific questions are tackled, we often don’t have much data. Conversely, successful machine learning (ML) tends to rely on large, high quality ...

The original version of this story appeared in Quanta Magazine. For computer scientists, solving problems is a bit like mountaineering. First they must choose a problem to solve—akin to identifying a ...
