Entangled photon sources (EPSs) are pivotal in advancing quantum communication, computing, and sensing. The demand for deploying efficient, robust EPSs the field, characterized by exceptional (phase) stability, has become increasingly apparent. This work introduces a polarization-entangled source, leveraging type-0 spontaneous parametric downconversion constructed using commercial bulk optomechanical components. Our system is versatile, enabling generation of N00N states sensing applications...
Quantum resources can provide supersensitive performance in optical imaging. Detecting entangled photon pairs from spontaneous parametric down conversion (SPDC) with single-photon avalanche diode (SPAD) image sensor arrays (ISAs) enables practical wide-field quantum-enhanced However, matching the SPDC wavelength to peak detection efficiency range of complementary metal-oxide-semiconductor (CMOS) compatible mass-producible SPAD-ISAs has remained technologically elusive, resulting low imaging...
Abstract Propagation of light by Anderson localization has been demonstrated in micro-nano-structured fibers. In this work, we introduce a phase separated glass optical fiber for quantum applications. By using spontaneous parametric down-conversion source, multi-photon detection with single-photon avalanche diode array camera, and signal post-processing techniques, demonstrate transport, where spatial correlations between photon pairs are preserved after propagation. order to better...

Quantum technology promises improvements in imaging, computing, and communication, for example using the resource of entanglement between photons with spatial correlations. Detecting correlations, or coincidences, entangled scalably, efficiently, affordably is therefore an essential capability. However, this task non-trivial existing camera technologies, which require low illumination intensities detection duty cycles to count coincidences at high signal-to-noise ratios, resulting long...
