Effect of random telegraph noise on entanglement and nonlocality of a qubit-qutrit system

Blog Article

We study the evolution of entanglement and nonlocality of a non-interacting qubit-qutrit system under the effect of random telegraph noise (RTN) in independent and common environments in Markovian and non-Markovian regimes.We investigate the dynamics of qubit-qutrit system for different lock shock and barrel art initial states.These systems could be existed in far astronomical objects.

A monotone decay of the nonlocality (entanglement) is found in the Markov regime, while for non-Markovian noise, phenomena of sudden change (death) and revival occurs.We find that the preserving nonlocality (entanglement) depends on initial state of the system in common and independent environments; so, we can not strictly conclude that bempresas.com independent or common environments are more robust against the noise.
