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 ...

A bosonic qubit developed by Nord Quantique. Made of aluminum, these cavities now contain two tiny "poles", each operating at a different frequency. These additional ...

In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum error correction, something that will be needed for the ...
