Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic ...

Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

Photon-number-resolving detection of quantum states of light by transition edge sensors. Machine learning methods can be used to improve the sensors' detection rate, while maintaining high efficiency, ...

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.

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

Recent progress in both analog and digital quantum simulations heralds a future in which quantum computers could simulate — and thereby illuminate — physical phenomena that are far too complex for ...
