This Demonstration shows the time-evolution (the Glauber-Sudarshan representation of the oscillator over time) and the participation ratio (a measure of the entanglement) of a system that consists of a quantum harmonic oscillator coupled with a delta pulse applied to a two-level system. The system is originally unentangled and in thermal equilibrium with the environment. The parameter , the decoherence parameter, depends on the strength of the coupling of the system with a Markovian bath.
