Résumé
We have generalised an all-optical telecorrection protocol for the higher orders of the cat code, and show that with these higher orders we can achieve target performance at substantially reduced iteration counts at the cost of a higher mean photon-number. We also introduce a probabilistic scheme for correcting deformation of the state, which highlights two interesting abilities of telecorrection: to encode new sets of transformations, and to change the basis of the code. We find that for a target channel fidelity of 99.9% over a channel with 1dB of loss, a third-order cat code requires 70 times fewer telecorrection iterations than a first-order one, at a cost of a 3.6-fold increase in mean photon-number.
