We establish a general condition which must be obeyed by every operator referred to the quantum phase. This condition is derived on the basis of the model of the linear phase insensitive amplifier, proposed by Glauber. We demonstrate that the phase operators, most frequently discussed in ...
A simple approach for this involves the application of the so-called single channel Caves model (SC-CM) for a phase-insensitive linear amplifier or attenuator. However, for complicated atomic systems with multiple degrees of freedom, the validity of this model has not been established. In this ...
摘要: This paper proposes a phase-insensitive fiber parametric amplifier system that outputs a phase-clamped signal. It consists of an orthogonally pumped fiber with polarization-aligned signal and a fiber loop with a polarization beam splitter....
We prove that a strong converse theorem holds for the classical capacity of all phase-insensitive bosonic Gaussian channels, when imposing a maximum photon number constraint on the inputs of the channel. The pure-loss, thermal, additive noise, and amplifier channels are all in this class of cha...

An expression is obtained for the corresponding level of noise by this amplifier. This noise level is greater than the level required in a previous paper which did not impose the non-reciprocal requirement. The synthesis procedure uses a singularly perturbed quantum system and leads to an ...
We demonstrate superior performance of a two-pump amplifier with respect to the state of the art EDFA in a low-input-power regime for the first time. A parametric amplifier with 50dB gain outperforms the EDFA by 1.5dB at FEC threshold level for a 10.7-Gb/s DPSK format.23rd Annual ...
