Entropy Squeezing in the Quantum Heisenberg XY Spin Chains

  • School of Science, Beijing Institute of Technology, Beijing 100081, China

  • Received Date:2007-10-26
    Abstract
  • The time evolution of entropy squeezing for the two-qubit XYZ Heisenberg model in an external uniform magnetic field is investigated in the language of quantum information. The effect of different parameters such as magnetic field and anisotropy parameter on the properties of entropy squeezing and variance squeezing are discussed. It is shown that magnetic field and anisotropy parameter can enhance the entropy squeezing.
