Design and performance analysis of photonic quantum teleportation circuit

Abstract

Abstract This paper presents the analytical investigation of the Fidelity and Concurrence of Photonic Quantum teleportation Circuit (PQTC) designed using quantum dot within the optical micro-cavity, considering vacuum noise and sideband leakage. It is found that the performance of the Photonic Quantum teleportation Circuit is significantly dependent on the interaction between the spin of quantum dot and photon within the optical cavity. The maximum concurrence obtained is 0.8158 at \(g/k=5\) and \({k}_{s}/k=0.1\) without noisy environment and 0.375 at \(g/k=0.3\) and \({k}_{s}/k=0.1\) with a noisy environment. The computed maximum fidelity of 0.99 is observed at \(g/k=4\) and \({k}_{s}/k=0.1\) with noisy conditions, and 0.4603 is observed at \(g/k=0.3\) and \({k}_{s}/k=0.1\) without noisy conditions. The work reported in this paper can be used to implement different quantum cryptography-based protocols.
