Abstract

V originále

We generalize the entanglement swapping scheme originally proposed for two pairs of qubits to an arbitrary number q of systems composed from an arbitrary number mj of qudits. Each of the systems is supposed to be prepared in a maximally entangled state of mj qudits, while different systems are not correlated at all. We show that when a set of qj = 1 aj particles (from each of the q systems aj particles are measured) is subjected to a generalized Bell-type measurement, the resulting set of qj = 1 (mj-aj) particles will collapse into a maximally entangled state.
