INTEGRATED PHOTONIC SYSTEM, QUANTUM FIELD PROGRAMMABLE PHOTONIC GATE ARRAY AND PROGRAMMABLE CIRCUITS

The present invention relates to an integrated photonic and quantum system realized by the combination and interconnection of Programmable Photonics Processing Blocks, implemented over a photonic chip that is capable of implementing one or multiple, simultaneous quantum and classical circuits with optical feedback paths and/or linear multiport transformations, by the appropriate programming of its resources and the selection of its input and output ports. The invention also relates to a quantum field-programmable photonic gate array (Q-FPPGA) comprising of, at least one programmable circuit based on tunable beam-splitters with independent coupling and phase-shifting configuration and peripheral high-performance building blocks enabling classical and quantum operations
