Entanglement assisted capacity of the broadband Lossy channel

Entanglement assisted capacity of the broadband Lossy channel

We calculate the entanglement assisted capacity of a multimode bosonic channel with loss. As long as the efficiency of the channel is above 50%, the superdense coding effect can be used to transmit more bits than those that can be stored in the message sent down the channel. Bounds for the other cap...
