Characterization and Control of Large-Scale Ion-Trap Quantum Computers

ORAL

Abstract

Performing Quantum Characterization, Verification, and Validation (QCVV) on large-scale ion-trap quantum computers is a challenging task because it requires a control system capable of quickly compiling and running large numbers of quantum circuits with minimal dead time. One limiting factor is the control hardware used for driving quantum gates: circuit waveforms for Arbitrary Waveform Generators (AWGs) are slow to compute and program, and Direct Digital Synthesizers (DDSs) are slow to modulate. These shortcomings can be addressed by parametric waveform generation, addressing the shortcomings of DDSs and AWGs, enabled by integration of RF output with an FPGA via a Xilinx RFSoC. We present integration of an RF System on a Chip (RFSoC) FPGA into our ion-trap quantum computer. We also present progress on using this new waveform generator to perform QCVV on a system with more than 10 qubits.
