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…
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…
