Abstract: A confinement assembly configured for confining quantum objects is provided. The confinement assembly includes a first substrate having potential generating elements formed thereon; and may include a second substrate that is secured with respect to the first substrate. The confinement assembly further includes at least a portion of a laser (e.g., gain media and at least part of a resonant structure) formed on the first and/or second substrate. The potential generating elements are operable for generating confinement regions configured for confining the quantum objects. The confinement assembly at least partially defines an optical path for causing an optical beam to interact with the at least a portion of the laser. The optical beam is (a) a seeding laser beam configured to control at least one property of light emitted by the laser or (b) an optical pumping beam configured to power the lasing activity of the laser.

Abstract: In various embodiments, a system comprising an atomic object confinement apparatus and one or more signal manipulation elements is provided. Each signal manipulation element (a) is associated with a respective atomic object position of the atomic object confinement apparatus and (b) is one of a collection array or an action array. A collection array is configured to, responsive to an emitted signal emitted by an atomic object at the respective atomic object position being incident on the collection array, provide an induced collection signal to a respective collection position. An action array is configured to, responsive to an incoming signal being incident on the action array, provide an induced action signal to the respective atomic object position. The one or more signal manipulation elements comprise metamaterial arrays and/or diffractive optical elements.

Abstract: A multi-frequency laser system comprises a master oscillator to generate a master beam and an arm splitter to split the master beam into a first beam and a second beam. The first beam is provided to a primary mode arm for generation of a primary mode beam and the second beam is provided to a sideband mode arm for generation of a sideband mode beam. The sideband beam arm comprises a modulator to modulate the second beam to generate a beam comprising sidebands; a filter to select a particular sideband mode from the beam comprising sidebands; an amplifier cavity to amplify the particular sideband mode and suppress other residual modes; and an acousto-optical modulator to shift the frequency of each mode of an amplified selected sideband beam to generate a sideband mode beam. The primary and sideband mode beams are provided in a coordinated manner to enact a quantum gate.
