Schrödinger-cat-like states for quantum fundamental solitons in optical fibers

Demin Yao

The generation of Schr\"odinger-cat-like states for quantum fundamental solitons in optical fibers is investigated. It is shown that the generation is possible at proper times in the dynamical evolution of an appropriately chosen initial state. Such a Schr\"odinger-cat-like state has a minimum number of components, three, and the superposition coefficients of components are all real. Mean values of the field and the intensity operators are calculated and the associated quantum interference behavior characteristic of quantum coherent superposition in the Schr\"odinger-cat-like states is revealed. The effect of dissipation on the Schr\"odinger-cat-like states is analyzed using a beam splitter. The severity with which losses tend to destroy interference between components of the input Schr\"odinger-cat-like state is noted.

Quantum-mechanical stability of solitons and the correspondence principle

Franz X. Kärtner, H. A. Haus

A Hanbury Brown--Twiss experiment is described that is capable of demonstrating, in principle, the solitary behavior of a quantum soliton in an arbitrary fundamental soliton state. The relevant correlation functions are evaluated and show that the quantum noise does not cause a breakup of the solitons of the quantized nonlinear Schr\"odinger equation. For large photon numbers, the intensity autocorrelation function of the fundamental soliton becomes independent of certain momentum and photon-number distributions, which gives us a correspondence principle for the fundamental soliton. Whereas intensity-correlation measurements based on direct detection show essentially classical behavior for large photon numbers, homodyne-detection experiments can uncover quantum effects such as the generation of Schr\"odinger-cat solitons.
