Improving Clock Speed in the Quantinuum Helios Quantum Computer

Helios is Quantinuum’s latest commercially available quantum computer, based on a trapped-ion architecture that enables high-fidelity operations across 98 fully connected qubits. One scaling challenge with this architecture is the time cost incurred by sorting and cooling ions during each layer in a program. In this talk, we present results demonstrating how Helios parallelizes these operations to increase clock speed, thereby reducing memory errors and improving system-level performance.
