- Abstract summary: We introduce a super-sensitive phase imager, which uses space-polarization hyper-entanglement to operate over a large field-of-view without the need of scanning operation.
We show quantum-enhanced imaging of birefringent and non-birefringent phase samples over large areas, with sensitivity improvements over equivalent measurements carried out with equal number of photons.

- Abstract: Quantum techniques can be used to enhance the signal-to-noise ratio in
optical imaging. Leveraging the latest advances in single photon avalanche
diode array cameras and multi-photon detection techniques, here we introduce a
super-sensitive phase imager, which uses space-polarization hyper-entanglement
to operate over a large field-of-view without the need of scanning operation.
We show quantum-enhanced imaging of birefringent and non-birefringent phase
samples over large areas, with sensitivity improvements over equivalent
classical measurements carried out with equal number of photons. The practical
applicability is demonstrated by imaging a biomedical protein microarray
sample. Our quantum-enhanced phase imaging technology is inherently scalable to
high resolution images, and represents an essential step towards practical
quantum imaging.

We introduce a single-photon detector design operating in the microwave domain based on a weakly nonlinear metamaterial.
We show that the single-photon detection fidelity increases with the length of the metamaterial to approach one at experimentally realistic lengths.
In stark contrast to conventional photon detectors operating in the optical domain, the photon is not destroyed by the detection and the photon wavepacket is minimally disturbed.
