Path to Scale QCCD Architecture for Trapped Ion Quantum Computers

The quantum charge-coupled device (QCCD) architecture for trapped ions was first proposed more than 25 years ago to allow scaling up to large number of qubits while maintaining high-fidelity operations. Incorporated into Quantinuum's H2 commercial quantum computer are several scalable features such as electrode broadcasting, multi-layer RF routing, and MOT loading. In addition, transport of ions through multiple junctions have been demonstrated on multiple Quantinuum traps. In this talk, I will discuss these key technology demonstrations on our roadmap to scaling, as well as recent progress in integrated photonics and other enabling technologies.
