It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true.

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 ...

Washington is moving from grants to ownership. Several quantum-computing companies are in talks with the Commerce Department ...

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 ...

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 ...

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

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

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 ...

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 ...
