New quantum error-correcting codes and decoders for QuantumClifford.jl

QuantumClifford.jl provides a basic functionality for quantum error correction. Yet, some important classes of QECCs and their decoders remain to be implemented, particularly those developed recently, e.g., asymptotically good quantum low-density parity-check (QLDPC) and bivariate bicycle codes. During the GSoC, i.e., JSoC for Julia, we aim to incorporate them into the QuantumClifford.jl ecosystem. To this end, we will add the following new features: new QECCs (concatenated quantum code, random Clifford circuit code, and a selected set of QLDPC codes), new decoders (BP-OSD, mismatch decomposition decoder, and linear-time decoder for lifted product codes).
