Nonreciprocal quantum correlations and dense coding
Muzzamal Iqbal Shaukat · Physical Review A · 2022
We compute different quantifiers to analyze the spontaneous generation of entanglement for a unidirectional (nonreciprocal) two-two level system. We illustrate this approach by deriving the Markovian master equation in the Lindblad form. The numerical analysis of the unidirectional master equation enabled to obtain the steady-state concurrence. We explore the quantum dense coding between two spatially separated dipoles taking into account the collective damping effect. Our results reveal the sharp decline and then gradual increase in the dense coding capacity to reach a stable value. This procedure opens the possibility to implement this scheme for further applications in the field of quantum information theory.
