Abstract summary: We demonstrate the preservation of time-energy entanglement of near-IR photons through thick biological media and tissue. Using a Franson-type interferometer, we demonstrate interferometric contrast of over 0.9 in skim milk, 2% milk, and chicken tissue.

Abstract: We demonstrate the preservation of time-energy entanglement of near-IR photons through thick biological media ($\leq$1.55 mm) and tissue ($\leq$ 235 $\mu$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.

Fluorescence Lifetime Hong-Ou-Mandel Sensing [0.944419833997454]
We demonstrate a fluorescence lifetime measurement technique based on photon-bunching statistics with a resolution that is only dependent on the duration of the reference photon or laser pulse. We corroborate the effectiveness of the technique by measuring the Newtonian viscosity of glycerol/water mixtures by means of a molecular rotor having over an order of magnitude variability in lifetime.

On-chip quantum information processing with distinguishable photons [55.41644538483948]
Multi-photon interference is at the heart of photonic quantum technologies. Here, we experimentally demonstrate that detection can be implemented with a temporal resolution sufficient to interfere photons detuned on the scales necessary for cavity-based integrated photon sources. We show how time-resolved detection of non-ideal photons can be used to improve the fidelity of an entangling operation and to mitigate the reduction of computational complexity in boson sampling experiments.

Entangled two-photon absorption detection through a Hong-Ou-Mandel interferometer [0.0]
The ETPA process is detected based on the changes induced on the Hong-Ou-Mandel interferogram of two photons produced by a spontaneous parametric down conversion process. We present a detail model in which the sample is modeled as a filtering function which fullfills the energy conservation conditions required by ETPA.

We take advantage of a single-photon avalanche diode (SPAD) array camera, with over one thousand detectors, to simultaneously detect speckle fluctuations at the single-photon level. We then apply a deep neural network to convert the acquired single-photon measurements into video of scattering dynamics beneath rapidly decorrelating liquid tissue phantoms.

Near-ideal spontaneous photon sources in silicon quantum photonics [55.41644538483948]
Integrated photonics is a robust platform for quantum information processing. Sources of single photons that are highly indistinguishable and pure, that are either near-deterministic or heralded with high efficiency, have been elusive. Here, we demonstrate on-chip photon sources that simultaneously meet each of these requirements.
