Dynamical analysis of quantum linear systems driven by multi-channel multi-photon states

Dynamical steady States in driven quantum systems.

We derive dynamical equations for a driven, dissipative quantum system in which the environment-induced relaxation rate is comparable to the Rabi frequency, avoiding assumptions on the frequency dependence of the environmental coupling. When the environmental coupling varies significantly on the scale of the Rabi frequency, secular or rotating wave approximations break down. We avoid these appr...

Multi-scale Switching Linear Dynamical Systems

Switching linear dynamic systems can monitor dynamic systems that operate in different regimes. In this article we introduce a class of multi-scale switching linear dynamical systems that are particularly suited if such regimes form a hierarchy. The setup consists of a specific switching linear dynamical system for every level of coarseness. Jeffrey’s rule of conditioning is used to coordinate ...

CONTROL OF CHAOS IN A DRIVEN NON LINEAR DYNAMICAL SYSTEM

We present a numerical study of a one-dimensional version of the Burridge-Knopoff model [16] of N-site chain of spring-blocks with stick-slip dynamics. Our numerical analysis and computer simulations lead to a set of different results corresponding to different boundary conditions. It is shown that we can convert a chaotic behaviour system to a highly ordered and periodic behaviour by making on...

Quantum entanglement – multi-photon sources

Entanglement lies in the heart of almost all methods of quantum communication and computation. Efficient and economical generation of entangled states of light are of crucial importance for the success of future quantum communication applications. This article introduces the experimental methods to produce entangled light modes both in the discrete and continuous variable regime.
