Abstract
Systems, apparatus and methods for defining an impairment profile along a polarization quantum channel such as in terms of modal loss and decoherence. The disclosed impairment profile or characterization methods may be used as part of a tool such as to inform a network operator of a weakest span of the communication channel, thus facilitating optimal signal routing decisions.
