The Thermal Entanglement Effects of Heisenberg XY Model Under Non-uniform Magnetic Field
Zhang De-hua
In our paper,we study the thermal entanglement in three quibts under external magnetic field,using Heisenberg XY model,through method of density matrix.And We compute the entanglement-concurrence.We find the quantumquibt's entanglement behaviour under different external magnetic field at limit temperature.Base on our conclusion,one may realize quantum computation and get the most favourable entanglement by effective control on quantum bit through external magnetic field's adjusting.
