Role of Quantum Entanglement and Classical Correlation in Two-photon Imaging
Ping‐Xing Chen · Acta Sinica Quantum Optica · 2009
The correlated imaging is an interesting topic.Whether second correlated imaging is a pure quantum effect or classical effect is still implicit.One phenomenon of quantum theory or classical theory,which is an interesting topic.This paper analyses three correlated imaging schemes together.The first two schemes can be achieved by two-photon which is classical correlated or quantum entangled and the third one can only be achieved by entangled two-photon.Through the comparison of these schemes,we find that entangled two-photon which can be used in all the three schemes is correlated both in position and momentum.However,the classical correlated two-photon only correlate in position or momentum,and only can be used in one scheme.
