Quantum state engineering by non-deterministic noiseless linear amplification
arXiv:1901.10509 · doi:10.1103/PhysRevA.99.063823
Abstract
We address quantum state engineering of single- and two-mode states by means of non-deterministic noiseless linear amplifiers (NLAs) acting on Gaussian states. In particular, we show that NLAs provide an effective scheme to generate highly non-Gaussian and non-classical states. Additionally, we show that the amplification of a two-mode squeezed vacuum state (twin-beam) may highly increase entanglement.
