Abstract

In this paper, effects of the regular measurements on a noisy channel has been investigated. The strategy introduced by Bayat et al. [New J. Phys. 17, 103041 (2015)] is followed to suppress dephasing and dissipation effects in a noisy spin channel and generate long distance entanglement by global measurement on the channel. A regular global measurements performed on spin channel weakly coupled to the sender and receiver qubits via XX interaction. This scheme is applied for dephasing and dissipation in non-zero temperature processes separately and the results show enhancement amounts of achieved entanglement rather than the no-measurement approach.
