    Abstract: Atomic object confinement apparatuses that include RF busses and systems including atomic object confinement apparatuses that include RF busses are provided. An example atomic object confinement apparatus comprises RF rail electrodes and an RF bus electrode(s). The RF rail electrodes form a periodic array of confinement segments within a central zone of the atomic object confinement apparatus and the RF bus electrodes are disposed in a perimeter zone disposed about the central zone. The RF rail electrodes and the RF bus electrode(s) are configured to generate a substantially periodic array of trapping regions when an oscillating voltage signal is applied to the RF rail electrodes and the RF bus electrode(s).

    Abstract: An ion trap apparatus is provided. The ion trap apparatus comprises two or more radio frequency (RF) rails formed with substantially parallel longitudinal axes and with substantially coplanar upper surfaces; and two or more sequences of trapping and/or transport (TT) electrodes with each sequence formed to extend substantially parallel to the substantially parallel longitudinal axes of the RF rails. The two or more RF rails and the two or more sequences of TT electrodes define an ion trap. The two or more sequences of TT electrodes are arranged into a number of zones. Each zone comprises wide matched groups of TT electrodes and at least one narrow matched group of TT electrodes. A wide TT electrode is longer and/or wider in a direction substantially parallel to the substantially parallel longitudinal axes of the RF rails than a narrow TT electrode.

    Abstract: A method for cooling an atomic object is provided. The method includes controlling voltage sources to cause a confinement apparatus to confine the atomic object at a position defined by the confinement apparatus, where motion of the atomic object at the position defined by the confinement apparatus comprises contributions from one or more radial motional modes of the atomic object and contributions from one or more axial motional modes of the atomic object; and causing at least one first control signal to be provided to at least one control electrode of the plurality of control electrodes, where an oscillating potential is generated at the position defined by the confinement apparatus and configured to cause at least one radial mode of the one or more radial modes of the atomic object to couple to at least one axial mode of the one or more axial modes of the atomic object.

    Abstract: A controller is configured to control operation of a confinement apparatus comprising one or more radio frequency rails and a plurality of control electrodes. The controller comprises a processing element, non-transitory computer-readable memory storing computer-executable instructions. The computer-executable instructions are configured to, when executed by the processing element, cause the controller to at least identify a manipulatable object transport operation to be performed; obtain a set of voltage signal sequences corresponding to the manipulatable object transport operation to be performed from the voltage signal sequence library; and cause one or more voltage sources to apply respective voltage signal sequences of the set of voltage signal sequences corresponding to the manipulatable object transport operation to respective control electrodes of the plurality of control electrodes via respective filters. The set of voltage signal sequences is determined based at least in part on respective filter responses of the respective filters.

    Abstract: The disclosure provides an atomic object trap apparatus and a method of operating such. The atomic object trap apparatus comprises two or more radio frequency (RF) electrodes formed concentrically in a substantially elliptical shape; and three or more trapping and/or transport (TT) electrode sequences formed concentrically in a substantially elliptical shape. The two or more RF electrodes and the three or more TT electrode sequences define a substantially elliptically-shaped atomic object trap. At least one TT electrode sequence of the three or more TT electrode sequences is disposed concentrically between the two or more RF electrodes. Each RF electrode and TT electrode sequence is elliptically shaped such that each comprises two substantially parallel longitudinal regions and two arc-spanning beltway regions, the four regions forming a substantially elliptical shape. The method is directed to operating a quantum computing system comprising an example atomic object trap apparatus.
