    "abstract": "We demonstrate that two recent innovations in the field of practical quantum\nkey distribution (one-way autocompensation and passive detection) are closely\nrelated to the methods developed to protect quantum computations from\ndecoherence. We present a new scheme that combines these advantages, and\npropose a practical implementation of this scheme that is feasible using\nexisting technology.",
