Soliton microcombs -- phase-locked microcavity frequency combs have become the foundation of several classical technologies in integrated photonics, including spectroscopy, LiDAR, and optical computing. Despite predicted multimode entanglement across comb, experimental study quantum optics soliton microcomb has been elusive. In this work, we use second-order photon correlations to underlying pr...

All-quantum signal processing techniques are at the core of successful advancement most information-based quantum technologies. This article develops coherent and comprehensive methodologies mathematical models to describe Fourier optical in full terms for any input state light. We begin this by introducing a spatially 2-D photon, associated with its wavefront expressible as creation operator. ...

We compare two possible ways of defining a category 1-combs, the first intensionally as coend optics and second extensionally quotient by operational behaviour 1-combs on lower-order maps. show that there is full bijective objects functor quotienting intensional definition to extensional one give some sufficient conditions for this be an isomorphism categories. also how constructions can extend...
