Evaluation of entropy in multi-partite systems under local quantum noise channels
Ms Mahdiye Shams Javazm 1
Abstract:   (216 Views)

In the quantum information processing due to the unavoidable interaction of quantum systems with the environment, the decoherence phenomenon is occurred which leads to the reduction and finally decaying of quantum (non­classical) properties. Quantum correlations are one of the fundamental quantum properties. In this paper, we study a qutrit-qutrit system which is initially prepared in a maximally entanglement state by solving analytically the fundamental equation for noisy channels, i.e., dephasing and trip-flip. With the help of the entropy as a measure of entanglement, we show that in the transmission through the dephasing channel the entanglement is more preserved than the trip-flip channel.
