Superstrong coupling regime of cavity quantum electrodynamics

Calculation of Kolmogorov Entropy in Cavity Quantum Electrodynamics

In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...

Cavity quantum electrodynamics

The simplest model in quantum optics deals with a single two-level atom interacting with a single mode of the radiation field. This ideal situation is implemented in Cavity Quantum Electrodynamics experiments, using high quality microwave or optical cavities as photon boxes. It provides a test bench for fundamental quantum processes and a promising ground for quantum information processing.

Cavity QED and Quantum Computation in the Strong Coupling Regime

In this paper we propose a Hamiltonian generalizing the interaction of the two– level atom and both the single radiation mode and external field · · · a kind of cavity QED. We solve the Schrodinger equation in the strong coupling regime by making use of rotating wave approximation under new resonance conditions containing the Bessel functions and etc, and obtain unitary transformations of four ...

Cavity QED and Quantum Computation in the Weak Coupling Regime

In this paper we consider a model of quantum computation based on n atoms of laser–cooled and trapped linearly in a cavity and realize it as the n atoms Tavis– Cummings Hamiltonian interacting with n external (laser) fields. We solve the Schrödinger equation of the model in the case of n=2 and construct the controlled NOT gate by making use of a resonance condition and rotating wave approximati...
