Near-Optimal Covariant Quantum Error-Correcting Codes from Random Unitaries with Symmetries
Quantum error correction and symmetries play central roles in quantum information science and physics. It is known that quantum error-correcting codes that obey (are covariant with respect to) continuous symmetries in a certain sense cannot correct erasure errors perfectly (a well-known result in th...
