Effects of Quantum Noise on Teleportation of an Arbitrary Two-Qubi t State via a Five-Particle Brown State

Abstract We propose an innovative protocol for quantum teleportation (QT) which employs the Brown state as the quantum channel. Our study focuses on the teleportation of a single unknown two-qubit state via a Brown state channel in an ideal environment. To validate the effectiveness of our proposed scheme, we conduct experiments using the quantum circuit simulator Quirk. Furthermore, we investigate the impact of four noisy channels, namely the phase damping noise, the bit-flip noise, the amplitude damping noise and the phase-flip noise. Notably, we employ Monte Carlo simulation to elucidate the fidelity density under various noise parameters. Our analysis demonstrates that the fidelity of the protocol in a noisy environment is influenced significantly by the amplitude of the initial state and the noise factor.
