Please join us for the final AMO/QI seminar of the semester featuring Dr. Michael Mills of Quantinuum. He will be giving a talk titled: Benchmarking a racetrack trapped-ion quantum processor

Abstract:
The System Model H2, a quantum charge-coupled device (QCCD) trapped-ion system with a new racetrack-shaped trap, is Quantinuum's latest generation of quantum computers. The new system successfully incorporates several technologies crucial to future scalability, including electrode broadcasting, multi-layer RF routing, and magneto-optical trap (MOT) loading, while maintaining, and in some cases exceeding, the gate fidelities of previous QCCD systems.

We describe the operations in the H2 system and benchmark the performance of primitive operations, including single-qubit and two-qubit gate fidelity, state preparation and measurement fidelity, and crosstalk errors. Further, we highlight several applications using the H2 system, such as the creation of non-abelian topological order and anyons. Finally, we discuss upgrades to the H2 system.
