Solomon equations for qubit and two-level systems: Insights into non-Poissonian quantum jumps
Martin Spiecker, Andrei I. Pavlov, Alexander Shnirman +1
We measure and model the combined relaxation of a qubit coupled to a discrete two-level system~(TLS) environment, also known as the central spin model. If the TLSs are much longer-…
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…
Mitigating crosstalk errors by randomized compiling: Simulation of the BCS model on a superconducting quantum computer
Hugo Perrin, Thibault Scoquart, Alexander Shnirman +2
We develop and apply an extension of the randomized compiling (RC) protocol that includes a special treatment of neighboring qubits and dramatically reduces crosstalk effects cause…
