Directional Codes: a new family of quantum LDPC codes on hexagonal- and square-grid connectivity hardware

György P. Gehér, David Byfield, Archibald Ruban

The paper introduces directional codes, a new family of quantum LDPC codes designed for square- and hexagonal-grid superconducting hardware that use iSWAP gates to measure stabiliz…
