Ideal Quantum Communication over Noisy Channels: a Quantum Optical Implementation
S. J. van Enk, J. I. Cirac, P. Zoller
Abstract
We consider transmission of an (unknown) quantum state between two distant atoms via photons. Based on a quantum-optical realistic model, we define a noisy quantum channel which includes systematic errors as well as errors due to coupling to the environment. We present a protocol that allows one to accomplish ideal transmission by repeating the transfer operation as many times as needed.
