โœฆ Synopsis

An experimental scheme is suggested that permits a direct measure of entanglement in a two-qubit cavity system. It is realized in the cavity-QED technology utilizing atoms as flying qubits. With this scheme we generate two different measures of entanglement, namely logarithmic negativity and concurrence. The phenomenon of sudden death entanglement (ESD) in a bipartite system subjected to dissipative environment is examined. We show that the sudden death time of the entangled states depends on the initial preparation of the entangled state and the temperature of the reservoir.

The incoherent dynamics of a two-level system (TLS) coupled to a thermal bath and driven by a strong external periodic field is studied. Starting with the master equation for a dissipative TLS in an external field, we derive analytical expressions for the effective rate constant and for the apparent

This work is concerned with nearly optimal controls of nonlinear dynamic systems under the influence of singularly perturbed Markov chains. The underlying Markov chains have fast and slow components and their states can be divided into a number of groups. Within each group of states, the chain varie
