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

Make Excel evaluate your data for you.

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Another quantum computing record has been broken. A team has built a quantum computer with the largest ever number of so-called logical qubits, or quantum bits. Unlike standard qubits, logical qubits ...

This technique involves diagnosing and correcting errors while calculations are underway without destroying logical qubits. Because qubits process calculations while they're in a state of quantum ...
