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…
Anomalous low-energy properties in amorphous solids and the interplay of electric and elastic interactions of tunneling two-level systems
Alexander Churkin, Shlomi Matityahu, Andrii O. Maksymov +2
Tunneling two-level systems (TLSs), generic to amorphous solids, dictate the low-temperature properties of amorphous solids and dominate noise and decoherence in quantum nano-devic…

Shlomi Matityahu, Hartmut Schmidt, Alexander Bilmes +5
Increasing and stabilizing the coherence of superconducting quantum circuits and resonators is of utmost importance for various technologies ranging from quantum information proces…
Bond-counting potentials -- A classical many-body model of covalent bonding with exact solutions in one dimension
Shlomi Matityahu, Nathan Argaman
We introduce "bond-counting" potentials, which provide an elementary description of covalent bonding. These simplistic potentials are intended for studies of the mechanisms behind…
Rabi noise spectroscopy of individual two-level tunneling defects
Shlomi Matityahu, Jürgen Lisenfeld, Alexander Bilmes +4
Understanding the nature of two-level tunneling defects is important for minimizing their disruptive effects in various nano-devices. By exploiting the resonant coupling of these d…
Spin filtering in all-electrical three-terminal interferometers
Shlomi Matityahu, Amnon Aharony, Ora Entin-Wohlman +1
Unlike the two-terminal device, in which the time-reversal invariant spin-orbit interaction alone cannot polarize the spins, such a polarization can be generated when electrons fro…
Decoherence of a quantum two-level system by spectral diffusion
Shlomi Matityahu, Alexander Shnirman, Gerd Schön +1
We study the dephasing of an individual high-frequency tunneling two-level system (TLS) due to its interaction with an ensemble of low-frequency thermal TLSs which are described by…
Spin-dependent transport through a chiral molecule in the presence of spin-orbit interaction and non-unitary effects

Jürgen Lisenfeld, Alexander Bilmes, Shlomi Matityahu +7
Recent progress with microfabricated quantum devices has revealed that an ubiquitous source of noise originates in tunneling material defects that give rise to a sparse bath of par…
