Entanglement dynamics of two-level systems under decoherence — •Joachim Fischbach and Matthias Freyberger — Institut für Quantenphysik, Universität Ulm, D-89069 Ulm, Germany

While being one of the most intriguing effects in quantum physics, entanglement is also notoriously susceptible to the effects of noise. Thus we are interested in understanding the dynamics of entanglement under the influence of decoherence. In our work we study entanglement properties of two-level systems coupled to a cavity, altogether located in a noisy environment. In particular we examine the ultra-strong coupling regime between two-level systems and cavity as well as the possibility of creating entanglement via a dissipative state preparation.
