abstract
We investigate new features, especially of entanglement dynamics, which arise in a quantum–classical hybrid. As a model, we study the coupling between two quantum mechanical two-level systems, i.e., two q-bits and a classical harmonic oscillator. Their interaction is described by a hybrid coupling, in accordance with a recently developed quantum–classical hybrid theory. We discuss various situations in which entanglement of the q-bits does (not) evolve. Furthermore, we point out an experimental application in a hybrid cooling scheme and indicate topics for future study.
