Enabling Technologies for Scalable Superconducting Quantum Computing
Xanthe Croot, Kasra Nowrouzi, Christopher Spitzer +21
Experiments with superconducting quantum processors have successfully demonstrated the basic functions needed for quantum computation and evidence of utility, albeit without a siza…
Fail fast: techniques to probe rare events in quantum error correction
Michael E. Beverland, Malcolm Carroll, Andrew W. Cross +1
The ultimate goal of quantum error correction is to create logical qubits with very low error rates (e.g. 1e-12) and assemble them into large-scale quantum computers capable of per…
Tour de gross: A modular quantum computer based on bivariate bicycle codes
Theodore J. Yoder, Eddie Schoute, Patrick Rall +5
We present the bicycle architecture, a modular quantum computing framework based on high-rate, low-overhead quantum LDPC codes identified in prior work. For two specific bivariate…
Feedforward suppression of readout-induced faults in quantum error correction
Liran Shirizly, Dekel Meirom, Malcolm Carroll +1
Qubit measurements in quantum devices involve various types of errors, including erroneous state determination, correlated preparation errors and measurement-induced leakage from t…
Subsystem surface and compass code sensitivities to non-identical infidelity distributions on heavy-hex lattice
Malcolm S. Carroll, James R. Wootton, Andrew W. Cross
Logical qubits encoded into a quantum code exhibit improved error rates when the physical error rates are sufficiently low, below the pseudothreshold. Logical error rates and pseud…
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…
Dynamics of superconducting qubit relaxation times
Malcolm Carroll, Sami Rosenblatt, Petar Jurcevic +2
Superconducting qubits are a leading candidate for quantum computing but display temporal fluctuations in their energy relaxation times T1. This introduces instabilities in multi-q…
