Estimating the error of an analog quantum simulator by additional measurements
Iris Schwenk, Sebastian Zanker, Jan-Michael Reiner +2
We study an analog quantum simulator coupled to a reservoir with a known spectral density. The reservoir perturbs the quantum simulation by causing decoherence. The simulator is us…
Electronic Decoherence of Two-Level Systems in a Josephson Junction
Alexander Bilmes, Sebastian Zanker, Andreas Heimes +5
The sensitivity of superconducting qubits allows for spectroscopy and coherence measurements on individual two-level systems present in the disordered tunnel barrier of an $\mathrm…
Decoherence and Decay of Two-level Systems due to Non-equilibrium Quasiparticles
Sebastian Zanker, Michael Marthaler, Gerd Schön
It is frequently observed that even at very low temperatures the number of quasiparticles in superconducting materials is higher than predicted by standard BCS-theory. These quasip…
Decoherence spectroscopy with individual two-level tunneling defects
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…
