Effects of classical fluctuating environments on decoherence and bipartite quantum correlations dynamics
arXiv:2107.11241 · doi:10.1088/1555-6611/ac2ccf
Abstract
We address the time evolution of the quantum correlations () such as entanglement, purity, and coherence for a model of two non-interacting qubits initially prepared as a maximally entangled bipartite state. We contrast the comparative potential of the classical fields to preserve these in the noisy and noiseless realms. We also disclose the characteristic dynamical behavior of the of the two-qubit state under the static noisy effects originating from the common and different configuration models. We show that there is a direct connection between the fluctuations allowed by an environment and the preservation. Due to the static noisy dephasing effects, the are suppressed, resulting in the separability of the two-qubit entangled state after a finite duration. Here, the decay effects are found much smaller in the common configuration model than that of the opponent. Furthermore, this protection of the under static noise for large intervals is entirely attributable to the existence of the entanglement sudden death and birth phenomenon. Most importantly, we found the bipartite less fragile than the tripartite ones in comparison under the static noise. In the case of the measures, the concurrence is found to be sharper for showing the entanglement sudden death and birth revivals in comparison to the purity and decoherence.
