Abstract

This study reports an experimental realization of non-local classical optical correlation from the Bell's measurement used in tests of quantum non-locality. Based on such a classical Einstein–Podolsky–Rosen optical correlation, a classical analogy has been implemented to the true meaning of quantum teleportation. In the experimental teleportation protocol, the initial teleported information can be unknown to anyone and the information transfer can happen over arbitrary distances. The obtained results give novel insight into quantum physics and may open a new field of applications in quantum information.

Summary

Introduction

This study reports an experimental realization of non-local classical optical correlation from the Bell’s measurement used in tests of quantum non-locality. Based on such a classical Einstein–Podolsky–Rosen optical correlation, a classical analogy has been implemented to the true meaning of quantum teleportation. A non-separable classical correlation is called ‘‘nonquantum entanglement’’ or ‘‘classical entanglement’’25–30 Such a classical entanglement has been applied to resolve basic issues in polarization optics[25], simulate quantum walks, et al.[27]. We present a new method to construct a non-local classical EPR correlation state by using two incoherent light beams and implement a classical analogy on the true meaning of quantum teleportation
