Abstract

The problem of the impossibility of completely describing the quantum entanglement of a system of many particles only with the biparticle entanglement of the constituent subsystems is treated. The numerical procedure of the selection of a contrary instance and the results of the procedure are described. It is also shown that the measure of the entanglement of pure states on the basis of the minimization of the entropy of measurements is essentially a multiparticle measure; i.e., this measure of entanglement cannot be expressed in terms of the Schmidt coefficients.
