Witnessing the survival of time-energy entanglement through biological tissue and scattering media
arXiv:2102.12907 · doi:10.1364/BOE.423743
Abstract
We demonstrate the preservation of time-energy entanglement of near-IR photons through thick biological media (1.55 mm) and tissue ( 235 m) at room temperature. Using a Franson-type interferometer, we demonstrate interferometric contrast of over 0.9 in skim milk, 2% milk, and chicken tissue. This work supports the many proposed opportunities for nonclassical light in biological imaging and analyses from sub-shot noise measurements to entanglement-enhanced fluorescence imaging, clearly indicating that the entanglement characteristics of photons can be maintained even after propagation through thick, turbid biological samples.
