Quebec-based quantum hardware startup Nord Quantique has launched a quantum error correction technique that reportedly increased the lifetime of a single quantum qubit by 14%.
The company implemented Gottesman-Kitaev-Preskill (GKP) bosonic codes on a single qubit to enhance its durability and rectify typical errors like bit-flips and phase-flips, reducing the necessity for additional physical qubits in error correction as the system scales up. This error management method could potentially lessen the requirement for physical qubits by 1,000x to 10,000x in comparison to other models.
