Entanglement dynamics of a Heisenberg chain with Dzyaloshinskii-Moriya interaction
《Chinese Physics B》2009年第8期3210-3214,共5页郑强 张小平 支启军 任中洲 
supported by the National Natural Science Foundation of China (Grant Nos 10535010,10775123 and 10865004);Research Fund of the Education Ministry of China (Grant No 20070284016)
This paper investigates the entanglement dynamics of the system, composed of two qubits A and B with Heisenberg XX spin interactation. There is a third controller qubit C, which only has Dzyaloshinskii-Moriya (DM) s...
