Abstract: Aspects of the present disclosure describe techniques for independently controlling an angle (e.g., change in tilt) and/or position (e.g., change in lateral position) of an optical beam. For example, an optical beam control system may include a telescope with rotatable mirrors and lenses configured to provide a path to an optical beam to produce an output optical beam, which in turn is made into parallel optical beams following a diffractive optical element. The optical beam control system may also include a detector system to a beam angle and/or a beam position of one of the parallel optical beams to generate feedback signal or signals to control a rotation of one or more of the mirrors in the telescope such as to adjust the beam angle, the beam position, or both of the parallel optical beams. The optical beam control system may be part of a quantum information processing (QIP) system.

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 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 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.

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.
