Reliable high-accuracy error mitigation for utility-scale quantum circuits
Dorit Aharonov, Ori Alberton, Itai Arad +36
Error mitigation is essential for unlocking the full potential of quantum algorithms and accelerating the timeline toward quantum advantage. As quantum hardware progresses to push…
Qubit dephasing by spectrally diffusing quantum two-level systems
Shlomi Matityahu, Alexander Shnirman, Moshe Schechter
We investigate the pure dephasing of a Josephson qubit due to the spectral diffusion of two-level systems that are close to resonance with the qubit. We identify the parameter regi…
Two-level system hyperpolarization using a quantum Szilard engine
Martin Spiecker, Patrick Paluch, Nicolas Gosling +16
The innate complexity of solid state physics exposes superconducting quantum circuits to interactions with uncontrolled degrees of freedom degrading their coherence. By using a sim…
Experimentally revealing anomalously large dipoles in a quantum-circuit dielectric
Liuqi Yu, Shlomi Matityahu, Yaniv J. Rosen +5
Quantum two-level systems (TLSs) intrinsic to glasses induce decoherence in many modern quantum devices, such as superconducting qubits. Although the low-temperature physics of the…
Stabilization of Qubit Relaxation Rates by Frequency Modulation
Shlomi Matityahu, Alexander Shnirman, Moshe Schechter
Temporal, spectral, and sample-to-sample fluctuations in coherence properties of qubits form an outstanding challenge for the development of upscaled fault-tolerant quantum compute…
