Maximum Entanglement

A novel variational principle in quantum mechanics defining maximum entangled states (MES) in terms of quantum fluctuations of observables specifying these states was discussed. This principle was similar to the maximum entropy principle in statistical mechanics. It defines quantum entanglement as a physical phenomenon irrespective of information processing and other possible applications of entanglement. The revelation of the physical nature of maximum entanglement provided by the maximum scale of quantum fluctuations of the corresponding states gives a clue in the problem of stabilization of entanglement
