Fast-driving spectroscopy of current-phase relationships of individual Josephson elements
Maxim Tjøtta, Devashish Shah, Kanishk Modi +4
Extracting the current-phase relationship (CPR) of a single superconducting junction is challenging in practice and traditionally involves embedding the junction in a larger superc…
Machine-learned tuning to protected states by probing noise resilience
Rodrigo A. Dourado, Nicolás Martínez-Valero, Jacob Benestad +3
Protected states are promising for quantum technologies due to their intrinsic resilience against noise. However, such states often emerge at discrete points or small regions in pa…
Measuring coherence factors of states in superconductors through local current
Rodrigo A. Dourado, Jeroen Danon, Martin Leijnse +1
The coherence factors of quasiparticles in a superconductor determine their properties, including transport and susceptibility to electric fields. In this work, we propose a way to…
Real-time adaptive tracking of fluctuating relaxation rates in superconducting qubits
Fabrizio Berritta, Jacob Benestad, Jan A. Krzywda +17
The fidelity of operations on a solid-state quantum processor is fundamentally bounded by environmental decoherence. Characterizing environmental fluctuations is challenging becaus…
Phonon- and magnon-mediated decoherence of a magnonic qubit
Vemund Falch, Arne Brataas, Jeroen Danon
We investigate the decoherence of magnonic qubits in small ferromagnetic insulators and compute the relaxation and dephasing rates due to magnon-phonon and magnon-magnon interactio…
Efficient Qubit Calibration by Binary-Search Hamiltonian Tracking
Fabrizio Berritta, Jacob Benestad, Lukas Pahl +14
We present and experimentally implement a real-time protocol for calibrating the frequency of a resonantly driven qubit, achieving exponential scaling in calibration precision with…
