A beam delivery system is provided that includes a beam delivery photonic integrated circuit. The beam delivery photonic integrated circuit includes one or more optical inputs; a plurality of waveguide outputs; and a plurality of beam paths. Each beam path connects one of the plurality of waveguide outputs to at least one of the optical inputs. The plurality of waveguide outputs are configured to emit a plurality of parallel beams. The beam delivery photonic integrated circuit is on a chip. The beam delivery system further includes a telecentric optical relay assembly. The telecentric optical relay assembly is configured to receive the plurality of parallel beams provided by the waveguide outputs and focus each received beam on a corresponding one of a plurality of positions of an atomic object confinement apparatus in a telecentric manner.

Beam delivery system

Provided is a novel beam delivery system for quantum computing applications that includes a beam delivery photonic integrated circuit on a chip and an optical relay assembly. The beam delivery photonic integrated circuit on a chip may contain one or more layers, and a layer may contain one or more inputs connecting one or more outputs. The optical relay assembly receives a beam or beams from one or more outputs from a layer of the beam delivery photonic integrated circuit. The optical relay assembly focuses each received beam on a corresponding position of an atomic object confinement apparatus.

Integrated passive/active modulator units, integrated passive/active modulators comprising one or more units, and corresponding methods of fabrication and use are provided. In an example embodiment, a unit comprises an upstream passive portion comprising a passive waveguide; a downstream passive portion comprising a continuation of the passive waveguide; and an active portion between the upstream passive portion and the downstream passive portion. The active portion comprises an active waveguide and electrical contacts in electrical communication with the active waveguide. The active waveguide comprises an upstream taper and/or a downstream taper. The upstream taper is configured to optically couple the active waveguide to the passive waveguide of the upstream portion and the downstream taper is configured to optically couple the active waveguide to the continuation of the passive waveguide of the downstream portion.
