Abstract: A multi-atomic object crystal is transported from a first leg to a second leg of an atomic object confinement apparatus through a corresponding junction. Voltage sources in electrical communication with electrodes of the apparatus are controlled to confine the crystal in the first leg. The voltage sources are controlled to cause transport of the crystal along the first leg to proximate the junction and then to cause generation of a time-dependent potential at the junction that is configured to cause the crystal to traverse a transport path through the junction from the first leg to the second leg via a dynamic potential well. An order of atomic objects within the multi-atomic object crystal is changed as the multi-atomic object crystal traverses the transport path.

Abstract: An atomic object confined in a particular region of an atomic object confinement apparatus is cooled using an S-to-P-to-D EIT cooling operation. A controller associated with the atomic object confinement apparatus controls first and second manipulation sources to respectively provide first and second manipulation signals to the particular region. The first manipulation signal is characterized by a first wavelength corresponding to a transition between an S manifold and a P manifold of a first component of the atomic object and detuned from the S-to-P transition by a first detuning. The second manipulation signal is characterized by a second wavelength corresponding to a transition between the P manifold and a D manifold of the first component and detuned from the P-to-D transition by a second detuning. The first and second detunings selected to establish a dark state associated with a two-photon transition between the S manifold and the D manifold.

Voltage sources in electrical communication with electrodes of the apparatus are controlled to confine the crystal in the first leg. The voltage sources are controlled to cause transport of the crystal along the first leg to proximate the junction and then to cause generation of a time-dependent potential at the junction that is configured to cause the crystal to traverse a transport path through the junction from the first leg to the second leg via a dynamic potential well defining a particular variable axial frequency. The transport path is determined by combining a path of constant total confinement for a representative atomic object of the crystal and a path of radio frequency minimum for the representative atomic object, using a particular variable path ratio.

CPC classification number: H01J49/422 , G06N10/20
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.
