A quantifiable measure widely used is the "entanglement of formation" of a mixed state, defined as the minimum number of singlets needed to create an ensemble of pure states that represents the density matrix of the system. Considering a double quantum dot system coupled cavity type Jaynes-Cummings investigate the entanglement between two quantum dots, immersed each in its own cavity, showing analytically that entanglement has a very interesting effects such as temporal evolution including the so-called sudden death effect.

In this work, we develop a model of the interaction of a pair of entangled and coupled Quantum Dots (QDs), each one in its own micro cavity, interacting with its own particular classical field. We analyze the interaction with their specific classical coherent and thermal fields at the atomic variables and the Resonance Fluorescent (RF) spectrum of one of the QDs. We compare these results with the case when the QDs are not entangled. The field coherence properties of one of the QDs are shown in the evolution of the single population inversion and of the resonance fluorescent spectrum of each system, even in the case when they are not entangled, and we point out the differences due to the entanglement by comparing with the no entangled case
