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.

Devices, methods, and systems for enclosures for an ion trapping device are described herein. One enclosure for an ion trapping device includes a heat spreader base that includes a plurality of apertures. The ion trapping device may also include a grid array having a plurality of pins extending outward from a surface of the grid array. The apertures of the heat spreader base may be arranged such that the plurality of pins passes through the plurality of apertures.

Enclosure for ion trapping device

The present subject matter provides technical solutions for the technical problems facing cryogenic ion traps by providing a cryogenic radio-frequency (RF) resonator that is compact, monolithic, modular, and impedance-matched to a cryogenic ion trap. The cryogenic RF resonator described herein is power-efficient, properly impedance-matched to the RF source, has a stable gain profile, and is compatible with a low temperature and ultra-high vacuum environment. In some examples, the gain profile is selected so that the cryogenic RF resonator acts as a cryogenic RF amplifier. This cryogenic RF resonator improves the performance of ion traps by reducing or minimizing the heat load and reducing or minimizing the unwanted noise that may erroneously drive trapped ions. These features of the present subject matter improve the performance of atomic clocks and mass spectrometers, and especially improve the performance of trapped ion quantum computers.
