双光子成像与量子全息
Two-photon imaging and quantum holography
摘要:
有人声称,“在成像系统中使用纠缠光子可以表现出任何其他双光子源无法模仿的效果,无论两个光子之间的相关性如何”[A]。F.阿布拉迪湾E. A. Saleh,A. V. Sergienko和M. C. Teich,Phys. Rev. Lett. 87,123602(2001)]。虽然我们相信引用的陈述是正确的,但我们表明,该论文中提出的方法,其中一个光子的“桶检测”,将给出与适当准备的经典相关态相同的纠缠态结果。
英文摘要:
It has been claimed that ``the use of entangled photons in an imaging system can exhibit effects that cannot be mimicked by any other two-photon source, whatever strength of the correlations between the two photons'' [A. F. Abouraddy, B. E. A. Saleh, A. V. Sergienko, and M. C. Teich, Phys. Rev. Lett. 87, 123602 (2001)]. While we believe that the cited statement is true, we show that the method proposed in that paper, with ``bucket detection'' of one of the photons, will give identical results for entangled states as for appropriately prepared classically correlated states.
