Digital Predistortion for Flux Control of Tunable Superconducting Qubits
Dharun Venkateswaran, Felice Francesco Tafuri, Yuanzheng Paul Tan +8
Flux-tunable superconducting qubits rely on fast flux control pulses to implement two-qubit entangling quantum gates, a key building block for quantum algorithms. However, distorti…
Easier randomizing gates provide more accurate fidelity estimation
Debankan Sannamoth, Kristine Boone, Arnaud Carignan-Dugas +4
Accurate benchmarking of quantum gates is crucial for understanding and enhancing the performance of quantum hardware. A standard method for this is interleaved benchmarking, a tec…
A polar decomposition for quantum channels (with applications to bounding error propagation in quantum circuits)
Arnaud Carignan-Dugas, Matthew Alexander, Joseph Emerson
Inevitably, assessing the overall performance of a quantum computer must rely on characterizing some of its elementary constituents and, from this information, formulate a broader…
Randomized Benchmarking under Different Gatesets
Kristine Boone, Arnaud Carignan-Dugas, Joel J. Wallman +1
We provide a comprehensive analysis of the differences between two important standards for randomized benchmarking (RB): the Clifford-group RB protocol proposed originally in Emers…
Direct randomized benchmarking for multi-qubit devices
Timothy J. Proctor, Arnaud Carignan-Dugas, Kenneth Rudinger +3
Benchmarking methods that can be adapted to multi-qubit systems are essential for assessing the overall or "holistic" performance of nascent quantum processors. The current industr…
From randomized benchmarking experiments to gateset circuit fidelity: how to interpret randomized benchmarking decay parameters
Arnaud Carignan-Dugas, Kristine Boone, Joel J. Wallman +1
Randomized benchmarking (RB) protocols have become an essential tool for providing a meaningful partial characterization of experimental quantum operations. While the RB decay rate…
