“…One can consider Bell inequalities or generalizations thereof, perhaps to test local realism or just to show non-factorizability. Another approach to studying entanglement of these states is to recognize that unentangled coherent states have Gaussian statistics and then use the covariance properties to quantify the degree of entanglement in such states [146]. An alternative approach considers the entangling power of operations that produce entangled coherent states [56].…”

We review entangled coherent state research since its first implicit use in 1967 to the present. Entangled coherent states are important to quantum superselection principles, quantum information processing, quantum optics, and mathematical physics. Despite their inherent fragility they have produced in a conditional propagating-wave quantum optics realization. Fundamentally the states are intriguing because they are entanglements of the coherent states, which are in a sense the most classical of all states of a dynamical system. Contents

Abstract. Theoretical justification for the occurrence of multimode squeezed and entangled colour states in QCD is given. We show that gluon entangled states which are closely related with corresponding squeezed states can appear by the four-gluon self-interaction. Correlations for the collinear gluons are revealed two groups of the colour correlations which is significant at consider of the quark-antiquark pair productions.
