Perfect Coding for Dephased Quantum State Transfer
arXiv:1711.02314 · doi:10.1103/PhysRevA.97.032317
Abstract
We develop a family of perfect quantum error correcting codes that correct for phase errors that arise on any qubit, at any time, during a perfect state transfer experiment. These ensure that we find the optimal operating regime for corrected state transfer. For a specific class of system, we further show that while dephasing noise can be corrected, depolarising noise cannot.
