Abstract


From the last century since the creation of quantum information science , entangled states as quantum mechanics and classical mechanics is one significant difference in the study of basic theory of quantum mechanics has been widespread concern. People in quantum information and quantum computing has made a series of breakthroughs , making the international forefront of the discipline become hot . Quantum information and quantum computing as an important carrier of entanglement preparation and effective measures will naturally become the theoretical basis and experimental study of important issues. Atoms in an optical lattice systems are subject to spontaneous standing wave field dipole radiation and the role of being trapped in space , we can control the laser so as to control the optical lattice atoms purposes. This system can be very effective to achieve certain quantum information processing. This article discusses a system of nonlinear optical lattice quantum entanglement and thermal entanglement related issues. Firstly, detailing the basic theory of entangled states and entanglement measures , as well as in various fields of application . Specifically calculated and discussed the introduction of the system of two-body entanglement , and system dynamics corresponding entanglement capacity . Also studied architecture entanglement and thermal entanglement entanglement capacity . Finally the body is constructed of two EPR ??states and the two-body quantum flip door .
