 Stabilizer code

A stabilizer code is the common positive eigenspace of a commuting subgroup of the Pauli group.

Stabilizer codes are a class of quantum error-correcting codes that are used to protect quantum information from errors due to decoherence and other quantum noise. They are particularly important in quantum computing and quantum information theory because they provide a way to encode quantum bits (qubits) into larger systems in a way that allows for the detection and correction of errors.
