A quantum computer corrected its own errors, improving its calculations . It’s a step in the right direction for reliable quantum computing ...

In a pair of papers submitted June 17 at arXiv.org, researchers generated conditions called “magic states,” crucial components of quantum computations. And those magic states were high-quality enough ...

The complexity of a calculation a quantum computer can complete depends on the number of qubits it contains. Recently, IBM and California-based Atom Computing unveiled devices with more than 1000 ...

Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can ...

The feat, reported in Nature on 22 February, follows up on a celebrated 2019 experiment in which a Google quantum computer achieved ‘quantum advantage’ — by performing a calculation that ...

This time around, the company is showing that it can get an actual logical qubit into a variant of the same hardware. In the ...

The 56-qubit H2-1 computer has broken the previous record in the 'quantum supremacy' benchmark first set by Google in 2019. When you purchase through links on our site, we may earn an affiliate ...
