Anderson localization, a strong localization effect that prevents wave diffusion, is fundamentally important in manipulating wave propagation in a disordered medium. This work uses a phase separated glass Anderson localization optical fiber and demon

The generation of non-classical light states in the near-infrared (NIR) is important for a number of photonic quantum technologies. Here, we report the first experimental observation of sub-Poissonian NIR (1.24 eV) light emission from defects in a 2D

We present a widefield quantum polarised light microscope, illuminating with a NOON state (N=2) and imaging using a SPAD array camera. Compared to classical imaging we show that sensitivity improves by a factor of 1.31.

In this work we do a brief analysis of some widespread technologies for imaging science and security, while we also propose new techniques to exceed their standard classical limits by using quantum illumination and quantum detection, and exploiting s

Breakdown flashes in single-photon avalanche diodes can adversely affect low-level-photon experiments. We present the first measurement of this phenomenon at telecom wavelengths which is essential to the design and implement of preventive measures.

Breakdown flashes are undesired photo-emissions from the active area of single-photon avalanche photo-diodes. They arise from radiative recombinations of hot carriers generated during an avalanche and can induce crosstalk, compromise the measurement
