Paper Abstract

The analysis of formation of chaotic quantum states for two (or four) orthogonally polarized modes in a tunnelly-coupled optical fiber has been carried out. A special attention is devoted both to the structure of arising polarization instabilities and to the possibility to control of such a quantum state by procedure of quantum nondemolition measurements. New effect of polarization switching is obtained and we discuss the problem of both coding of information and construction of quantum logical elements for quantum computing. The optical schemes to realize the quantum AND (NOT-AND), OR (NOT-OR) and controlled-NOT gates with quantum nondemolition filtering of the signal are proposed.
