Quantum Holography (imaging) Through Entanglement - Getting an image without sensing the interacting photons.
Fig. 1. Classical and quantum holography. (A) In classical holography, the spatially dependent interference pattern of two coherent beams, the reference beam and the object beam, after interaction with the object, are recorded and used to construct the hologram of the object. (B) In our quantum holography scheme, we make use of two-photon states that can be generated by SPDC in one of two sources. The spatial shape of the object, which is transferred to the spatial shape of the light reflected/transmitted from the object, is contained in the probability amplitudes corresponding to the paired photons being generated in either of two SPDC sources.
This article is about reporting on experimental results that are really mind-blowing. This experiment is reported in “Quantum Holography with undetected light”. in “Science Advances” To quote part of the…
