Binary communication in entangled channels
Matteo G A Paris
abstract: We analyze optical binary communication assisted by entanglement and show
that: i) ideal entangled channels have smaller error probability than ideal
single-mode coherent channels if the photon number of the channel is larger
than one; ii) realistic entangled channels with heterodyne receivers have
smaller error probability than ideal single-mode coherent channels if the
photon number of the channel is larger than a threshold of about five photons.
