Demonstration of quantum volume 64 on a superconducting quantum computing system

2020 · arXiv (Cornell University)

We improve the quality of quantum circuits on superconducting quantum computing systems, as measured by the quantum volume, with a combination of dynamical decoupling, compiler optimizations, shorter two-qubit gates, and excited state promoted readout. This …

Classical benchmarking of zero noise extrapolation beyond the exactly-verifiable regime

2023 · arXiv (Cornell University)

In a recent work a quantum error mitigation protocol was applied to the expectation values obtained from circuits on the IBM Eagle quantum processor with up $127$ - qubits with up to $60 \; - …

Error mitigation with stabilized noise in superconducting quantum processors

2024 · arXiv (Cornell University)

Pre-fault tolerant quantum computers have already demonstrated the ability to estimate observable values accurately, at a scale beyond brute-force classical computation. This has been enabled by error mitigation techniques that often rely on a representative …
