On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

A quantum computer has demonstrated that it can solve a problem more efficiently than a conventional computer. This achievement comes from being able to unlock a vast memory resource that classical ...

Here, the team led by Lidar used an algorithm they modified for the quantum computer to solve a variation of "Simon's problem," an early example of quantum algorithms that can, in theory, solve a task ...

Mikel Díez, Director of Quantum Computing at IBM Spain, explains how the new quantum systems will work alongside classical ones to offer new possibilities for problem-solving. The Basque city of San ...

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 ...

Google researchers have made a fresh claim of quantum advantage — the ability of quantum computers to radically speed up calculations compared with their classical counterparts. This is not the ...

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.

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

The year isn't over yet, but we've already seen record-breaking quantum computers, skyrocketing levels of investment, and demonstrations of real-world benefits. In all the hype about AI it can be easy ...

Quantum computers hit a crucial milestone for error-free calculation The new record holder is a quantum computer called Jiuzhang 4.0 that makes calculations using particles of light, or photons.
