Correction is not possible with one parity bit since any bit error in any position creates exactly the same information as bad parity. If more bits are integrated ...

Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...

A Google-led research team has demonstrated a surface-code logical qubit operating below the error-correction threshold, showing that logical errors can fall rapidly as the code scales up. The ...

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 ...

Two years after the original press-release announcement, independently peer-reviewed results published in Nature on June 10, 2026, have confirmed that Microsoft and ...
