- Abstract summary: Light-field microscopy (LFM) is a 3D microscopy technique whereby information of a sample is gained in a single shot.
In this work, we demonstrate a LFM design that does not require a trade-off between position and angular resolution.
We demonstrate that a resolving power of 5$mu$m can be maintained with a DOF of $sim500$$mu$m, over an order of magnitude larger compared to conventional LFM designs.

- Abstract: Light-field microscopy (LFM) is a 3D microscopy technique whereby volumetric
information of a sample is gained in a single shot by simultaneously capturing
both position and angular information of light emanating from a sample.
Conventional LFM designs require a trade-off between position and angular
resolution, requiring one to sacrifice resolving power for increased depth of
field (DOF) or vice versa. In this work, we demonstrate a LFM design that does
not require this trade-off by utilizing the inherent strong correlation between
spatial-temporal entangled photon pairs. Here, one photon from the pair is used
to illuminate a sample from which the position information of the photon is
captured directly by a camera. By virtue of the strong momentum/angular
anti-correlation between the two photons, the angular information of the
illumination photon can then be inferred by measuring the angle of its
entangled partner on a different camera. We demonstrate that a resolving power
of 5$\mu$m can be maintained with a DOF of $\sim500$$\mu$m, over an order of
magnitude larger compared to conventional LFM designs. In the extreme, at a
resolving power of 100$\mu$m, it is possible to achieve near infinite DOF

We propose BigFUSE, a global context-aware image fuser that stabilizes image fusion in light-sheet fluorescence microscopy (LSFM)

Imaging systems measuring intensity in the far field succumb to Rayleigh's curse, a resolution limitation dictated by the finite aperture of the optical system.
Many proof-of-principle and some two-dimensional imaging experiments have shown that, by using spatial mode demultiplexing (SPADE), the field information collected is maximal.

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.

Quantum imaging is well-suited to study sensitive samples which require low-light conditions, like biological tissues.
In this context, interaction-free measurements (IFM) allow us infer the presence of an opaque object without the photon interacting with the sample.
Here we extend the IFM imaging schemes to multi-pixel, semi-transparent objects, by encoding the information about the pixels into an internal degree of freedom.
