Trapped-ion qutrit spin molecule quantum computer

D. Mc Hugh, Jason Twamley

We present a qutrit quantum computer design using trapped ions in the presence of a magnetic field gradient. The magnetic field gradient induces a 'spin–spin' type coupling, similar to the J-coupling observed in molecules, between the qutrits which allows conditional quantum logic to take place. We describe in some detail how one can execute specific one and two qutrit quantum gates, required for universal qutrit quantum computing.

Quantum Computing With Trapped Ions: An overview

Wen-Han Png, Ting Hsu, Tze-Wei Liu +2 more

An array of trapped atomic ions that are laser cooled and isolated in an ultrahigh-vacuum environment presents one of the most advanced physical platforms for realizing a practical quantum computer. Small-scale ion quantum computers up to tens of ions have been built and achieved the highest fidelities on elementary quantum operations and overall quantum volume (QV). This article provides an overview of the elements of trapped-ion quantum computing (TIQC), current achievements in the field, and future perspectives.

Reconfigurable and Programmable Ion Trap Quantum Computer

Stewart Allen, Jungsang Kim, David L. Moehring +1 more

We present progress on the construction and operation of a room- temperature quantum computer built with trapped atomic ion qubits. Based on the technological underpinnings of atomic clocks that define time, atomic qubits are standards of quantum information because they are all identical. They present a fundamentally scalable approach to quantum computation where interactions can be faithfully replicated and measured with near-perfect efficiency. Moreover, the connection among atomic ion qubits are forged from external laser beams and mediated by the Coulomb repulsion between them, and hence behave as a fully reconfigurable quantum circuit, much like an FPGA in classical computation. We further discuss paths to scaling using demonstrated technologies that are unique to this class of quantum computation devices. This flexibility will likely allow ion trap quantum computers to express the superset of all known quantum computation operations, and thus efficiently target any type of application that arises.

Scalable Arrays of Micro-Penning Traps for Quantum Computing and Simulation

Shreyans Jain, Joseba Alonso, Matt Grau +1 more

We propose the use of two-dimensional Penning trap arrays as a scalable platform for quantum simulation and quantum computing with trapped atomic ions. This approach involves placing arrays of microstructured electrodes defining static electric quadrupole sites in a magnetic field, with single ions trapped at each site and coupled to neighbors via the Coulomb interaction. We solve for the normal modes of ion motion in such arrays and derive a generalized multi-ion invariance theorem for stable motion even in the presence of trap imperfections. We use these techniques to investigate the feasibility of quantum simulation and quantum computation in fixed ion lattices. In homogeneous arrays, we show that sufficiently dense arrays are achievable, with axial, magnetron, and cyclotron motions exhibiting interion dipolar coupling with rates significantly higher than expected decoherence. With the addition of laser fields, these can realize tunable-range interacting spin Hamiltonians. We also show how local control of potentials allows isolation of small numbers of ions in a fixed array and can be used to implement high-fidelity gates. The use of static trapping fields means that our approach is not limited by power requirements as the system size increases, removing a major challenge for scaling which is present in standard radio-frequency traps. Thus, the architecture and methods provided here appear to open a path for trapped-ion quantum computing to reach fault-tolerant scale devices.
