了解重影干扰

Understanding Ghost Interference

Tabish Qureshi, Pravabati Chingangbam, Sheeba Shafaq

摘要:

利用波包动力学理论分析了纠缠光子的鬼干涉现象。结果表明,鬼干涉是由于纠缠而产生的虚双缝和干涉光子的路径信息的量子擦除的综合效应。对于两个光子颜色不同的情况,研究表明干涉光子的条纹宽度不仅取决于其自身的波长,还取决于与其纠缠的另一个光子的波长。

英文摘要:

The ghost interference observed for entangled photons is theoretically analyzed using wave-packet dynamics. It is shown that ghost interference is a combined effect of virtual double-slit creation due to entanglement, and quantum erasure of which-path information for the interfering photon. For the case where the two photons are of different color, it is shown that fringe width of the interfering photon depends not only on its own wavelength, but also on the wavelength of the other photon which it is entangled with.
