Abstract
In this work, we demonstrate the preservation of time-energy entanglement of near-IR photons through thick biological media (< 1.55 mm) and tissue (< 235 um) at room temperature. Using a Franson-type interferometer, we demonstrate interferometric contrast of over 0.90 in skim and 2% milk as well as chicken tissue. This work supports the many proposed opportunities for non-classical light in biological imaging and analyses, clearly indicating that the entanglement characteristics of photons can be maintained even after propagation through thick, turbid biological samples.Citation
