Improving noiseless linear amplification for optical quantum communication with quadrature squeezing

Song Yang, ShengLi Zhang, Xu‐Bo Zou +2 more

Quantum noiseless linear amplification (NLA) is an important tool for long-distance optical quantum communication. In this paper, we show that NLA with linear optics and photon counts can be further improved by applying quadrature squeezing. Moreover, we find that such enhancement through squeezing can be observed even when a photon dichotic on-off detector and a pseudo-single-photon state are applied to the amplification process. Such a result could find more applications in already-known NLA-related quantum information tasks.

Noiseless amplification in cavity-based optical systems with an internal two-photon process. I. General approach

L. A. Lugiato, A. Pregnolato, Lorenzo Spinelli

We study the features of noiseless amplification in a general class of optical systems, characterized by an intracavity nonlinearity which induces a two-photon process, in the limit where the damping constant of the mode which undergoes the two-photon process greatly exceeds all other relaxation rates of the system. By applying a previously formulated analytical approach, we write the universal-form expressions for the linear amplification factor and the noise figure. Noiseless amplification is attainable under resonance conditions.
