A Plug-and-Play Universal Photonic Processor for Quantum Information Processing.

Taballione

Large-scale and programmable quantum photonic processors are needed to control photonic quantum computations that lead to a quantum advantage. Here, we present a universal 12-mode quantum photonic processor which is the largest of its kind to date. The processor is remotely controllable and seamlessly integrated with a dedicated control software, making the device fully plug-and-play.

Integrated universal linear optical networks are essential for the development of quantum information processing (QIP). We demonstrate a universal, reconfigurable, 8×8 photonic processor based on Si3N4 waveguides showing a variety of QIP primitives.

Abstract Photonic processors are pivotal for both quantum and classical information processing tasks using light. In particular, linear optical quantum information processing requires both large-scale and low-loss programmable photonic processors. In this paper, we report the demonstration of the largest universal quantum photonic processor to date: a low-loss 12-mode fully tunable linear interferometer with all-to-all mode coupling based on stoichiometric silicon nitride waveguides.
