Neural decoders for subsystem many-hypercube codes
Ryota Nakai, Hayato Goto
To maximize the potential of quantum error-correcting codes, it is essential to develop high-performance decoders. The subsystem many-hypercube (MHC) codes have been developed to a…

Subsystem many-hypercube codes: High-rate concatenated codes with low-weight syndrome measurements
Ryota Nakai, Hayato Goto
Quantum error-correcting codes (QECCs) require high encoding rate in addition to high threshold unless a sufficiently large number of physical qubits are available. The many-hyperc…
