Architectural Features of the IonQ Tempo Quantum Computer

To date, the ion trap quantum computers developed by IonQ utilize a single long chain of ions. This limits the number of qubits one can reasonably address with high fidelity Molmer-Sorenen gates. We overcome this limitation via multi-parcel operation (MPO) – ions are partitioned into reasonably sized sub-chains ("parcels"), and we introduce a minimal amount of shuttling to shift, split, and merge parcels together to perform computations on larger qubit registers. We present on the progress of implementing the MPO architecture, including other architectural features such as single-species OMG qubits, which enable scaling the number of qubits via MPO in our quantum computers.
