Nondeterministic Noiseless Linear Amplification of Quantum Systems
arXiv:0809.0326 · doi:10.1063/1.3131295
Abstract
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 two applications; ideal probabilistic cloning of coherent states and distillation of continuous variable entanglement. For the latter example we demonstrate that highly pure entanglement can be distilled from transmission over a lossy channel.
