We build a test setup for metrological characterization of the qCMOS photon number-resolving camera. We evaluate the quality of the photon number distributions measured with the camera for coherent and pseudo-thermal sources and perform quantum tomography of the camera. Further, we make measurements of multiple spatially overlapping pseudo-thermal states to perform full statistical mode reconstruction and calculate the spatial distribution of the high-order correlation functions $g^{(n)}(0)$. We use the obtained results to demonstrate spatio-angular super-resolution with a photon number-resolving camera. The methods reported here can be used as a toolkit for quantum super-resolving microscopy with photon number-resolving cameras.
We investigate the coexistence of clock synchronization protocols with quantum signals propagating in a common optical single-mode fiber channel. By measuring optical forward and backward scattering noise in a range from 1510 nm to 1620 nm we demonstrate a potential for up to 100 quantum channels each with 100 GHz bandwidth coexisting with the classical synchronization signals using off-the-shelf optical components. Both “White Rabbit'' and a pulsed laser-based synchronization were characterized and compared.
