Benchmarking Quantum Processor Performance at Scale
David C. McKay, Ian Hincks, Emily J. Pritchett +3
As quantum processors grow, new performance benchmarks are required to capture the full quality of the devices at scale. While quantum volume is an excellent benchmark, it focuses…
Native two-qubit gates in fixed-coupling, fixed-frequency transmons beyond cross-resonance interaction
Ken Xuan Wei, Isaac Lauer, Emily Pritchett +3
Fixed-frequency superconducting qubits demonstrate remarkable success as platforms for stable and scalable quantum computing. Cross-resonance gates have been the workhorse of fixed…
Floquet Analysis of Frequency Collisions
Kentaro Heya, Moein Malekakhlagh, Seth Merkel +2
Implementation of high-fidelity gate operations on integrated-qubit systems is of vital importance for fault-tolerant quantum computation. Qubit frequency allocation is an essentia…
Using Cryogenic CMOS Control Electronics To Enable A Two-Qubit Cross-Resonance Gate
Devin L. Underwood, Joseph A. Glick, Ken Inoue +18
Qubit control electronics composed of CMOS circuits are of critical interest for next generation quantum computing systems. A CMOS-based application specific integrated circuit (AS…
Characterizing non-Markovian Off-Resonant Errors in Quantum Gates
Ken Xuan Wei, Emily Pritchett, David M. Zajac +2
As quantum gates improve, it becomes increasingly difficult to characterize the remaining errors. Here we describe a class of coherent non-Markovian errors -- excitations due to an…
Algorithms for perturbative analysis and simulation of quantum dynamics
Daniel Puzzuoli, Sophia Fuhui Lin, Moein Malekakhlagh +3
We develop general purpose algorithms for computing and utilizing both the Dyson series and Magnus expansion, with the goal of facilitating numerical perturbative studies of quantu…
