Abstract
The quantum nonlocality sexual people feel wonderful feature of the quantum theory. And the classical theory, quantum theory (nonrelativistic quantum mechanics to relativistic quantum field theory) with a local description of the method, but in essence, quantum theory is still in the local description of the space under the guise of nonlocal theory . Nonlocality wonderful nature is to show up more and more, and is experiencing a growing number of experimental test. The study of quantum nonlocality of the fundamental problems of quantum theory and quantum information theory is meaningful. The paper is divided into six chapters. The first chapter provides a brief to study quantum nonlocality history and some important results. The second chapter describes the basic theory of nonlocal quantum; including the EPR paradox and quantum mechanics completeness; Bell Inequality and destruction; extended CHSH inequality and its greatest damage. The highlight is the Bell inequality theorem. Chapter entangled coherent state quantum nonlocality; entangled coherent state is one of the entangled state of continuous variables can be prepared in a few experiments. Depth understanding of research it can not only continuous variable entangled state the nature of the nonclassical, as well as explore the nonlocal nature of photons between the multiple associated. This chapter first introduces the calculation entangled coherent state quantum nonlocality two common methods. Then propose a new approach, that is, based on the parity coherent states constitute Ying spin operator can make the BellCHSH inequality breaches value reaches its upper limit 2 ^{ 1/2 , while in the experiment having the possibility of realization. After found entangled coherent state in theory to obtain the optimal nonlocal Bell operator. Chapter IV study a twomode less the k photons compression vacuum state of quantum nonlocality; minus k photons twomode squeezed vacuum state is entangled states of continuous variables can be prepared in another experiment. It is nonGaussian quantum state can be used for the nonlocality experimental test. This chapter focuses on the use of the Ying spin operator acting on a twomode minus k photon BellCHSH inequality Squeezed Vacuum States, found that less photons means you can enhance the state of nonlocality. Then further study the impact of decoherence on the state of the BellCHSH inequality. The fifth chapter describes the Bell inequality quantum nonlocality theorem; first four chapters are introduced with a Belltype inequality theorem. The Cabello given this chapter GHZ along inequalities, Hardy and Cabello theorem to do an overview, and then propose a new continuous variables
