Secure direct communication using the 'polarization' entangled atomic ensembles

  • 1. Key Laboratory of Quantum Information, University of Science and Technology of China, Hefei 230026 (China)

Description

We propose a scheme with potential experimental realization to generate 'polarization' entanglement between two atomic ensembles and show one of the applications - a novel secure communication allowing asymptotically key distribution and quasisecure direct communication. The scheme involves laser manipulation of atomic ensembles, adjustable quarter- and half-wave plates, beam splitters, polarizing beam splitters and single-photon detectors, and well fits the status of the current experimental technology
