To Quantum Optics
The theory of quantum propagator and time–dependent integrals of motion in quantum optics is reviewed as well as the properties of Wigner function, Q– function, and coherent state representation. Propagators and wave functions of a free particle, harmonic oscillator, and the oscillator with varying frequency are studied using time–dependent linear in position and momentum integrals of motion. S...
متن کاملApplication of Quantum Inequalities to Quantum Optics
We establish a connection between quantum inequalities, known from quantum field theory on curved spacetimes, and the degree of squeezing in quantum-optical experiments. We prove an inequality which binds the reduction of the electric-field fluctuations to their duration. The bigger the level of fluctuation-suppression the shorter its duration. As an example of an application of this inequality...
متن کاملThe quantum-jump approach to dissipative dynamics in quantum optics
Dissipation, the irreversible loss of energy and coherence, from a microsystem is the result of coupling to a much larger macrosystem (or reservoir) that is so large that one has no chance of keeping track of all of its degrees of freedom. The microsystem evolution is then described by tracing over the reservoir states, which results in an irreversible decay as excitation leaks out of the initi...
