Nonlocal entanglement analysis using quantum dot and microcavity coupled system

摘要

We propose an optimal nonlocal entanglement analysis protocol for a two-electron system exploiting the quantum dot and microcavity coupled system, resorting to the projective measurement on the entangled photon pair. The maximally entangled states can, in principle, been distinguished by two nonlocal parties without destroying them, which will improve the efficiency of long-distance quantum communication.
