Abstract: Aspects of the present disclosure describe techniques for optical alignment using a reflective dove prism. For example, a system for optical alignment is described that includes an assembly having a housing with three separate, reflecting structures positioned to produce three reflections of one or more laser beams or one or more images, and a controller configured to control a rotation of the assembly about a pivot point to produce a tilt in orientation of the one or more lasers beams or the one or more images that is twice an angle of rotation of the assembly. Another system and a method for aligning laser beams using a housing with three separate, reflecting structures in a trapped ion quantum information processing (QIP) system are also described.

Abstract: The disclosure describes various aspects of a tunable, mechanically stable radio-frequency (RF) amplifier. More specifically, the disclosure describes an RF amplifier designed to be tunable and mechanically stable to match and maintain stable driving of an ion trap for quantum processing applications. A precision actuator is used to finely tune the RF amplifier input in a repeatable and mechanically stable way to match the ion trap resonance. Low-loss tangent materials and torch annealing techniques are used to make the amplifier section mechanically stable.

Abstract: The disclosure describes various aspects of different for automated testing of optical assemblies. A system is described that includes an arm (e.g., a motorized arm) configured to be positioned over an optical assembly having a base plate with multiple optical elements that form one or more optical beam paths. The system also includes at least one optical tool that is configured to be removably attached to the arm and has a measurement instrument to perform a specified test on at least one of the optical beam paths. The arm is configured to adjust its position over the optical assembly to move the optical tool to the correct place to perform the specified test. The system may also include an optical tool changer configured to hold the optical tool in a tool holder when not attached to the arm and to hold additional optical tools in respective tool holders.

Abstract: Aspects of the present disclosure relate generally to parallel sideband cooling of multiple trapped-ion motional modes with deflectors (e.g., acousto-optic deflectors or AODs) in quantum information processing (QIP) systems. A method and a system are described in which for an ion chain a first group of ions (e.g., middle section of the ion chain) and a second group of ions (e.g., outer sections of the ion chain) are identified. The method and system include performing sideband cooling by applying, to the first group of ions, a first pair of optical beams using a first pair of AODs, and applying, to the second group of ions, a second pair of optical beams using a second pair of AODs. For each AOD, an acousto-optic modulator (AOM) may be placed upstream to provide frequency modulation for matching frequency differences for correct detuning as part of the sideband cooling operation.

Abstract: The disclosure describes aspects of laser cavity optical alignment, and more particularly, in situ alignment of optical devices in an optical system for replacement or upgrade. In one aspect, a method for optical alignment in an optical system is described that includes providing, via a positioning system, an optical beam to measure surface features and position of a first device under test (DUT), removing the first DUT from the optical system, placing a second DUT in the optical system at substantially the same position from which the first DUT was removed, providing, via the positioning system, an optical beam to measure surface features and position of the second DUT, aligning the second DUT based on the measurements made of the first DUT and the second DUT, and verifying operation of the second DUT in the optical system. The DUT can be an optical device such as an output optical coupler.

Abstract: The disclosure describes various aspects of techniques that can be used for making hermetic feedthroughs for enclosures. For example, a panel that provides a hermetic seal to a system enclosure can include an enclosure board made of a printed circuit board (PCB) and configured to have a size and shape that precisely covers an access to the system enclosure, the enclosure board including multiple inner connectors on an inner side of the PCB facing the inside of the system enclosure and multiple outer connectors on an outer side of the PCB facing the outside the system enclosure for feeding one or more of signals or fluids (e.g., gases, liquids, vacuum) through the PCB by having inner and outer connectors connected through the PCB. The panel may further include a gasket fitting the size and shape of the enclosure board and used with the enclosure board to provide the hermetic seal.

Abstract: The disclosure describes aspects of laser cavity repetition rate tuning and high-bandwidth stabilization of pulsed lasers. In one aspect, an output optical coupler is described that includes a cavity output coupler mirror, a piezoelectric actuator coupled to the cavity output coupler mirror, a locking assembly within which the cavity output coupler mirror and the piezoelectric actuator are positioned, and one or more components coupled to the locking assembly. The components are configured to provide multiple positional degrees of freedom for tuning a frequency comb spectrum of the pulsed laser (e.g., tuning a repetition rate) by adjusting at least one position of the locking assembly with the cavity output coupler mirror. A method of adjusting an output optical coupler in a pulsed laser is also described. These techniques may be used in different applications, including quantum information processing.

Abstract: The disclosure describes various aspects of a shed-resistant thermal atom source. More specifically, a thermal atom source is described for uniform thermal flux of target atomic species in which a metal wadding material is used as an intermediary surface for sublimation of the atoms, preventing the source material from shedding or dropping. In an aspect, a thermal atom source may include a container with closed and open ends, and inside a source material near the closed end and a wadding between the source material and the open end; a heater coupled to the closed end; one or more clamps configured to secure the container and the heater; and a current source coupled to the container and the heater to cause a temperature to increase such that a portion of the source material is released and diffuses to the open end through the wadding prior to being emitted as a flux.

Abstract: Aspects of the present disclosure describe an atomic oven including a cathode, an anode that comprises a source material, and a power supply that provides a voltage between the cathode and the anode, wherein applying the voltage causes multiple electrons from the cathode to ablate the source material from the anode or locally heat the anode to cause source material to evaporate from the anode and, in both case, to produce a stream of ablated or evaporated particles that passes through an opening in the cathode.

Abstract: The disclosure describes various aspects of different techniques for flexible touch sensors and method for wide-field imaging of an atom or ion trap. A touch sensor is described for controlling movement of a control element for use with the trap that includes an outer structure and an inner structure that holds the control element and moves within the outer structure. The trap is inside an ultra-high vacuum (UHV) environment and the outer and inner structures are outside the UHV environment and separated by a UHV window. The control element or elements are brought into proximity of the UHV window in connection with controlling targets at the trap. The inner structure can stop moving within the outer structure to avoid damaging of the UHV window with the control element(s) in response to the inner structure being in physical contact with or within a set proximity of the outer structure.
