Intrincamiento cuántico en ensambles de moléculas individuales acopladas

Abstract

We calculate the degree of entanglement dynamics of a pair of two-level (dipole) coupled molecules embedded in a dispersive medium of refraction index n which interact with the quantized radiation field and with an external coherent driving field. We compute the Concurrence in the generation of maximally entangled states and compare the results with other entanglement measures. We calculate the resonance fluorescence spectrum, obtaining an observable that provides direct evidence of the interaction between the single molecules. Our results consider energy scales, excitation frequencies, laser and dissipative refractive properties that can be realized with current technology.
