Quantum Correlations of Two Relativistic Spin- 1 2 $\frac {1}{2}$ Particles Under Noisy Channels

Abstract

We study the quantum correlation dynamics of bipartite spin- $\frac {1}{2}$ density matrices for two particles under Wigner rotations induced by Lorentz transformations which is transmitted through noisy channels. We compare quantum entanglement, geometric discord(GD), and quantum discord (QD) for bipartite relativistic spin- $\frac {1}{2}$ states under noisy channels. We find out QD and GD tend to death asymptotically but a sudden change in the decay rate of the entanglement occurs under noisy channels. Also, bipartite relativistic spin density matrices are considered as a quantum channel for teleportation one-qubit state under the influence of depolarizing noise and compare fidelity for various velocities of observers.
