Description

We show that multiqubit quantum channels which may be realised via stabilizer circuits without classical control (Clifford channels) have a particularly simple structure. They can be equivalently defined as channels that preserve mixed stabilizer states, or the channels with stabilizer Choi state. Up to unitary encoding and decoding maps any Clifford channel is a product of stabilizer state preparations, qubit discardings, identity channels and dephasing channels. This simple structure allows to characterise information-theoretic properties of such channels.
