Abstract: An apparatus has a plurality of photonic elements. At least two photonic elements forming a cavity. At least one photonic element receives first electromagnetic radiation from outside the cavity and transmits the first electromagnetic radiation into the photonic cavity. At least one photonic element receives second electromagnetic radiation from outside the cavity and transmits the second radiation into the photonic cavity. A photonic memory disposed in the cavity comprises an atomic system that: receives a photon field of first radiation; receives second radiation; stores at least a portion of the field of the photon in the atomic system via an atomic transition using the photon and the received second radiation; emits the stored portion of the photon upon receiving third electromagnetic radiation. The apparatus directs the photon into the photonic memory, after being reflected into the photonic cavity by at least one of the photonic elements; and outputs the emitted portion of the field into the cavity. The apparatus controls the photon flux density of the third electromagnetic radiation to control the superposition of the said stored field portion.

Abstract: Methods and systems are described herein for determining a solution to a binary optimization problem. In examples, a system described herein comprises a processor and a boson sampler which together implement a hybrid quantum-classical process. In an iterative process, parameters of the boson sampler are adjusted until a stopping condition is satisfied. After the stopping condition is met, a plurality of measurement outcomes are then produced by the boson sampler and mapped to binary sequences which are used to identify a solution to the binary optimization problem. Computer-readable media are also described herein.

Abstract: A system is provided for producing an output photon having a predefined frequency. A pump module produces a plurality of pump fields at a plurality of pump frequencies. A photon pair source module generates frequency-correlated photon pairs. A detector module generates a heralding signal subsequent to detecting a first photon of a photon pair, the heralding signal indicative of a frequency of the second photon of the pair. A non-linear photonic element is arranged to (1) receive the heralded second photon and a complementary selected pump field, and (2) to produce an output photon having the predefined frequency. A pump field selector is configured to (1) receive a heralding signal and (2) select, based on the received heralding signal, a pump field of the plurality of pump fields for provision to the non-linear element. Methods, controllers and computer-readable media are also described herein.

Abstract: A method of co-manufacturing silicon waveguides, SiN waveguides, and semiconductor structures in a photonic integrated circuit. A silicon waveguide structure can be formed using a suitable process, after which it is buried in a cladding. The cladding is polished, and a silicon nitride layer is disposed to define a silicon nitride waveguide. The silicon nitride waveguide is buried in a cladding, and annealed. Thereafter, cladding above the silicon waveguide structure can be trenched through, and low-temperature operations can be performed to or with an exposed surface of the silicon waveguide structure.
