Paradoxically, reports of powerful quantum computations are motivating improvements to classical ones, making it harder for quantum machines to gain an advantage. “Most of the time when people talk ...

A vital ingredient for making quantum computers truly useful just might be conventional computers. That was the message from a gathering of researchers this month, which explained that classical ...

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

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 ...

Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are ...

Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on ...

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 ...

Nvidia claims to have kicked off the “quantum-GPU computing era,” unveiling a way for quantum computers to interconnect with classical systems. Revealed at the chip giant’s GTC event in Washington, ...

International Business Machines (NYSE: IBM) has been working on quantum computing technology for decades. The company's quantum computing roadmap calls for a demonstration of quantum advantage, where ...

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 ...

The world of quantum computing has barged into a new frontier: space. A tiny quantum computer housed in a satellite is now in orbit around Earth, ScienceNews reports, residing some 330 miles above our ...
