Scientists have built a 98-qubit machine that they say performs better than any other quantum computer in the world. They've ...

Quantum computing is a revolutionary form of computing that uses the principles of quantum mechanics to perform calculations that would be infeasible or impossible for classical computers. Unlike ...

Quantum computing might seem like “just another” new technology, like the internet, cloud computing and AI. In fact, it’s something rather different – more similar to the leap forward from the ...

For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a particle's position and momentum cannot be known at the same time with absolute ...

Number of measurements required to learn about the behaviour of a complex, noisy quantum system reduced by a factor of 1011 ...

NPL is coordinating a broad-scope UK research initiative on performance metrics and benchmarking for quantum computers ...

A quantum computer qubit that is much more stable than current qubit designs, which are very error prone. Based on the theory of Italian physicist Ettore Majorana in ...

As of 2025, the quantum error rate is approximately one error per thousand gate operations. The goal is to achieve one error per trillion operations. See quantum ...

While quantum phenomena can be demonstrated using experiments such as the Double-Slit Experiment, certifying that a multi-qubit system is truly tapping into quantum mechanics is a challenge. It also ...
