Review of Entangled Coherent States

Abstract

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.

Comprehensive review of entangled coherent states. Comments welcome, especially advice on missing references or perhaps misrepresentations of existing references, which will be accommodated in version 2
