Existence and Characterisation of Bivariate Bicycle Codes

Understand

Encoding quantum information in a quantum error correction (QEC) code offers protection against decoherence and enhances the fidelity of qubits and gate operations.

• One of the fundamental challenges of QEC is to construct codes with asymptotically good parameters, i.e.
• a non-vanishing rate and relative minimum distance.
• Such codes provide compact quantum memory with low overhead and enhanced error correcting capabilities, compared to state-of-the-art topological error correction codes such as the surface or colour codes.
