A Quantum dot implanted within double-sided optical microcavity is explained and established as a critical component for all optical-based quantum internets. Due to the duality as the photonic quantum transistor and gate, the QD cavity system presents a sturdy base for the future photonic quantum network. With the help of the analytical investigation and review presented in this paper, a quantum dot cavity unit can be developed for implementing deterministic quantum gates and transistors. The maximum fidelity observed for quantum diode, router, and storage is 95.24%, 62.06%, and 90.42% without considering a noisy environment, respectively, and 62.12%, 60.36%, and 43.66% under a noisy environment, respectively. Fidelity is also calculated with varying coupling conditions (strong and weak coupling), and optimized cavity parameters are calculated. The paper also reports the work done by various researchers till date.

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.
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 ππ ππ β = .3 and ππ π π ππ β = 0.1 and 90.11 at ππ ππ β = 4 and ππ π π ππ β = 0.1 with and without noisy environment, respectively. Different quantum cryptography-based protocols may be implemented using reported work.
