Abstract Photonic processors are pivotal for both quantum and classical information processing tasks using light. In particular, linear optical requires large-scale low-loss programmable photonic processors. this paper, we report the demonstration of largest universal processor to date: a 12-mode fully tunable interferometer with all-to-all mode coupling based on stoichiometric silicon nitride waveguides.
In paraxial approximation, the electromagnetic eigenmodes inside an optical microresonator can be derived from a Schrödinger-type eigenvalue problem. this framework, tilting cavity mirrors introduces linear term to potential energy of system. our paper, we apply solution strategies for inverse problems precisely determine and control relative orientation two forming microcavity. Our approach employs inversion Schrödinger equation reconstruct effective landscape, thus mirror tilts, observed...
Josephson junctions are the basis for most sensitive magnetic flux detectors, definition of unit volt by voltage standard, and superconducting digital quantum computing. They result from coupling two coherent states, as they occur in superconductors, superfluids, atomic Bose-Einstein condensates, exciton-polariton condensates. In their ground state, characterised an intrinsic phase jump. Controlling this jump is fundamental applications Here, we experimentally demonstrate controllable...
Abstract The synchronization of coherent states light has long been an important subject basic research and technology. Recently, a new concept for analog computers emerged where this process can be exploited to solve computationally hard problems - potentially faster more energy-efficient than what achieved with conventional computer technology today. unit cell such systems consists two centers that are coupled one another in controlled manner. Here, we experimentally characterize analyze...
Abstract Open quantum systems can be systematically controlled by making changes to their environment. A well-known example is the spontaneous radiative decay of an electronically excited emitter, such as atom or a molecule, which significantly influenced feedback from emitter’s environment, for example, presence reflecting surfaces. prerequisite deliberate control open system reveal physical mechanisms that determine its state. Here, we investigate Bose-Einstein condensation photonic Bose...

Using widely different dispersion transverse supermodes a strongly-coupled dual-core section, using integrated pairs input output single-mode waveguides, we enable controlled excitation processes multiple supermodes, while basic physical mode decomposition aids the identification parallel cascaded processes. Pumping with ultrashort pulses at...
Recently, quantum advantage over classical computation has been claimed using photons [1] .
