Abstract

In this study the time evolution of entanglement between the terminal components of five or six-qubits spin chain under the effect of time-dependent magnetic fields is investigated. The interaction between the components of considered spin chain can be express with Heisenberg XX model. The most important result of this study is that if we want to have entanglement with high domain and low vibrations in an appropriate period of time; first, the magnetic field domain should be low, second, the magnetic field periodicity should be low and third we have to give enough time to the system to increase entanglement domain of the system.
