Abstract: Aspects of the present disclosure may include a method and/or a system for identifying an ion chain having a plurality of trapped ions, selecting at least two non-consecutive trapped ions in the ion chain for implementing a qubit, applying at least a first Raman beam to shuttle at least one neighbor ion of the at least two non-consecutive trapped ions from a ground state to a metastable state, and applying at least a second Raman beam to one or more of the at least two non-consecutive trapped ions, after shuttling the at least one neighbor ion to the metastable state, to transition from a first manifold to a second manifold.

Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to provide a cold finger for use with a quantum information processing (QIP) system including a cryostat. The cold finger includes a planar base including a first surface proximate a cooling plate of the cryostat opposite a second surface; a finger including a first end coupled to the second surface of the planar base and a second end configured to engage an ion trap; and an isolation unit positioned above the cooling plate of the cryostat and including a dielectric crystal plate that is configured to isolate the ion trap from electrical noise generated by the cryostat when controlling a temperature of the ion trap.

Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, including trapped-ion QIP systems. A technique is described in which it is possible to detect at the end of a computational sequence whether an ion has undergone a transition to a state outside a computational subspace, which can only happen because of a spontaneous emission event or other error, referred to as subspace leakage errors. By detecting instances in which the ion finishes the computation outside the computational subspace and subsequently rejecting the results of those specific runs, it is possible to mitigate some or all of the infidelity caused by the subspace leakage errors.
