A quantum computer made of charged atoms can catch its own errors when performing any operation – a meaningful step towards more reliable and practical quantum computers. Conventional computers ...

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 be ...

To shrink error rates in quantum computers, sometimes more is better. More qubits, that is. The quantum bits, or qubits, that make up a quantum computer are prone to ...

There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

It's possible to calculate the standard error in MATLAB by running a one-line command. Standard error is a measurement of the variability of a data set and how ...

The idea that quantum computers might one day solve complex problems at lightning speed on microscopic chips has long been touted. But the race to show that these processors can outperform their ...
