Entanglement generation for non-local photonic Qubits using quantum dot within the optical micro-cavity

Abstract

This paper presents the analytical inquisition of photonic entanglement generation circuit (PEGC) for non local Qubits designed using quantum dot within the optical micro-cavity, considering practical environment. It is established that the concurrence of the PEGC is considerably contingent on the interplay between spin of quantum dot and photon within the optical micro-cavity. The maximum concurrence obtained is 61.24 at \(g/k=.3\) and \({k}_{s}/k=0.1\) and 90.11 at \(g/k=4\) and \({k}_{s}/k=0.1\) with and without noisy environment, respectively. Different quantum cryptography-based protocols may be implemented using reported work.
