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.

Apparatuses, systems, and methods for ion traps

A quantum computer comprises an apparatus having atomic objects therein; a first manipulation source configured to provide a first manipulation signal; a second manipulation source configured to provide a second manipulation signal; and a controller. The controller is configured to cause the first manipulation source to provide the first manipulation signal to a region of the apparatus; and cause the second manipulation source to provide the second manipulation signal to the region. The first manipulation signal is tuned to excite atomic objects within the region from a leaked state outside of the qubit space to an intermediary manifold and to suppress excitation of atomic objects that are in the qubit space. The second manipulation signal is tuned to excite atomic objects from the intermediary manifold to a decay manifold from which there is a non-zero probability that an atomic object will decay into the qubit space.

Suppressing/transforming leakage errors in hyperfine qubits

A quantum computing D-state AC-Stark shift gate system comprises at least one gate manipulation source and one or more ions trapped in an ion trap. The at least one gate manipulation source is configured to generate a first gate manipulation signal and a second gate manipulation signal. The first and second gate manipulation signals couple an ion between a set of S-states and a set of D-states. The first and second gate manipulation signals apply a force to an ion of the one or more ions that is dependent on the internal state of the ion. The first and second gate manipulation signals are configured to couple internal states of the ions to their motional state without appreciably altering a population of the ions within the set of S-states.
