Ideal Quantum Communication over Noisy Channels: a Quantum Optical Implementation
arXiv:quant-ph/9702036 · doi:10.1103/PhysRevLett.78.4293
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.
