A Protocol for Conversion of Path-Spin to Spin-Spin Quantum Entanglement

Abstract

The present model deals with a protocol which involves the generation and conversion of entanglement from pathspin (P-S) hybrid entanglement associated with half-spin particle to spin-spin (S-S) interparticle entanglement. This protocol finds its applications in quantum information processing via a series of operations which include a beam splitter, spin flipper, spin measurement, classical channel, unitary transformations. Finally, it leads to two particles having completely entangled spin variables, without any requirement of any simultaneous operation on the two particles.
