Abstract: Aspects of the present disclosure describe techniques for mitigating charging on optical windows. For example, a device for mitigating charges inside a chamber of a trapped ion system is described that includes an array of parallel wires formed from a single, conductive plate by cutting elongated gaps through an entire thickness of the conductive plate that separate the wires, an outer portion of the conductive plate to which the wires are attached is configured to position the wires to run parallel to one or more trapped ions in the chamber and to position the wires between a dielectric component of the chamber and the one or more trapped ions. A chamber with such an array of parallel wires and a method of using such an array of parallel wires are also described.

Abstract: The disclosure describes various aspects of techniques for cooling a chain of ions to near the combined ground state that does not grow with the number of ions in the chain. By addressing each ion individually and using each ion to cool a different motional mode, it is possible to cool the motional modes concurrently. In an example, a third of the total motional modes can be cooled at the same time. In an aspect, the techniques include generating a sideband cooling laser beam for each ion in the ion chain, concurrently cooling two or more motional modes associated with the ions in the ion chain using the respective sideband cooling laser beam until each of the two or more motional modes reaches a motional ground state, and performing a quantum computation using the ion chain after the two or more motional modes have reached the motional ground state.

Abstract: The disclosure describes various aspects of a vibrationally isolated cryogenic shield for local high-quality vacuum. More specifically, the disclosure describes a cryogenic vacuum system replicated in a small volume in a mostly room temperature ultra-high vacuum (UHV) system by capping the volume with a suspended cryogenic cold finger coated with a high surface area sorption material to produce a localized extreme high vacuum (XHV) or near-XHV region. The system is designed to ensure that all paths from outgassing materials to the control volume, including multiple bounce paths off other warm surfaces, require at least one bounce off of the high surface area sorption material on the cold finger. The outgassing materials can therefore be pumped before reaching the control volume. To minimize vibrations, the cold finger is only loosely, mechanically connected to the rest of the chamber, and the isolated along with the cryogenic system via soft vacuum bellows.

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.

Abstract: The disclosure describes various aspects of acousto-optic modulator (AOM) configurations for quantum processing. A method is described including generating, by a first AOM from a laser beam, first and second diffracted laser beams at different angles based on first and second radio frequency (RF) tones. An optical component focuses the diffracted laser beams onto a second AOM, which generates third and fourth diffracted laser beams based on the first RF tone and a third RF tone and the second RF tone and a fourth RF tone respectively, wherein the third and fourth diffracted laser beams are substantially parallel when incident on a respective ion in a chain of ions in a trap. Quantum information in the ion is controlled to perform quantum processing based on the third and fourth diffracted laser beams. Another method is described including generating, by an AOM, a small polarization rotation of an undiffracted laser beam.

Abstract: Aspects of the present disclosure may include a method and/or a system for spatially aligning microfabrication processes and laser writing processes on a wafer by preparing a pattern of alignment features across a wafer with known relative locations and orientations between elements of the pattern, aligning one or more laser writing processes to the alignment patterns, laser writing features into the wafer based on the prior process alignment, aligning one or more microfabrication processes to the microfabrication alignment patterns, and processing the wafer via the microfabrication steps using the results of the prior alignment step.

Abstract: The use of multiple ion chains in a single ion trap for quantum information processing (QIP) systems is described. Each chain can have its own set of laser beams with which to implement and operate quantum gates within that chain, where each chain may therefore correspond to a single quantum computing register or core. Operations can be performed in parallel across all of these chains as they can be treated independently from each other. To implement and operate quantum gates between different chains, neighboring chains are merged into a single, larger chain, in which one can perform quantum gates between any of the ions in the larger chain. The combined chains can then be separated again by another shuttling event as needed. To implement and operate quantum gates between ions which do not occupy neighboring chains, swap gates can be used via a sequence of intervening chains.

Abstract: A shaped central electrode is described that is placed between a pair of radio frequency (RF) rails of a trap configured to hold atomic-based qubits to control aspects of the operation of the trap. In one aspect, the shaping may involve forming a pinched region in the middle of the central electrode. The middle of the central electrode may correspond to the middle portion of the trap. The shaping of the central electrode may be achieved in different ways and may involve varying the width of the central electrode. The trap may be fabricated on a glass die or substrate, which itself may be shaped or not. The trap may be fabricated by various methods such as, but not limited to, patterned metal layers on glass or silicon substrates. A quantum information processing (QIP) system is also described that may include a trap having any of these features.
