摘要： A package-level, integrated high-vacuum ion-chip enclosure having improved thermal characteristics is disclosed. Enclosures in accordance with the present invention include first and second chambers that are located on opposite sides of a chip carrier, where the chambers are fluidically coupled via a conduit through the chip carrier. The ion trap is located in the first chamber and disposed on the chip carrier. A source for generating an atomic flux is located in the second chamber. The separation of the source and ion trap in different chambers affords thermal isolation between them, while the conduit between the chambers enables the ion trap to receive the atomic flux.

摘要： The disclosure describes various aspects of techniques for elliptical beam design using cylindrical optics that may be used in different applications, including in quantum information processing (QIP) systems. In an aspect, the disclosure describes an optical system having a first optical component having a first focal length, a second optical component having a second focal length and aligned with a first direction, and a third optical component having a third focal length and aligned with a second direction orthogonal to the first direction. The optical system is configured to receive one or more optical beams (e.g., circular or elliptical) and apply different magnifications in the first direction and the second direction to the one or more optical beams to image one or more elliptical Gaussian optical beams. A method for generating elliptical optical beams using a system as the one described above is also disclosed.

摘要： 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.
