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 ...
The company’s surface code technique allows its quantum bits to faithfully store and manipulate data for longer, which could pave the way for useful quantum ...
A new technical paper titled “Quantum error correction below the surface code threshold” was published by researchers at Google and other collaborators.
