Quantum Error-Correcting Codes with a Covariant Encoding

Author(s): Aurélie Denys and Anthony Leverrier Given some group $G$ of logical gates, for instance the Clifford group, what are the quantum encodings for which these logical gates can be implemented by simple physical operations, described by some physical representation of $G$? We study this question by constructing a general form of such encod… [Phys. Rev. Lett. 133, 240603] Published Wed Dec 11, 2024
