Nondeterministic Noiseless Linear Amplification of Quantum Systems
T. C. Ralph, A. P. Lund, Alexander Lvovsky · AIP conference proceedings · 2009
We introduce the concept of non‐deterministic noiseless linear amplification. We propose a linear optical realization of this transformation that could be built with current technology. We discuss the application of the device to distillation of continuous variable entanglement. We demonstrate that highly pure entanglement can be distilled from transmission over a lossy channel.
