Entanglement in Classical and Quantum Statistics

Entanglement describes situations where two parts of a system are connected and cannot be separated. The properties in one part depend on the properties of the other part. The quantitative description of such situations is given by correlation functions. There is no conceptual difference between entanglement in classical statistics and entanglement in quantum mechanics [185]. In this chapter, we will explicitly construct probabilistic automata that realize the maximally entangled state of a twoqubit quantum system.
