Microwave Response of the Superconducting Diode Effect in Proximitized Bilayer Graphene Interferometers
Shili Yan, Rubén Seoane Souto, Yi Luo +7
Microwave irradiation has emerged as a promising means to tune the superconducting diode effect (SDE) in Josephson junction devices. Previous experimental studies have mainly focus…
Assessing Majorana states and qubits through quantum capacitance
Rodrigo A. Dourado, Ramón Aguado, Jeroen Danon +2
Quantum capacitance (QC) has recently emerged as a promising tool for parity readout in topological qubits based on Majorana bound states (MBSs). Here, we show that this capability…
Frequency-resolved decoherence spectroscopy of a semiconductor charge qubit coupled to a high-impedance resonator
Ekaterina Al-Tavil, Wonjin Jang, David J. van Woerkom +10
Superconducting resonators coupled to semiconductor quantum dots provide a powerful platform to investigate light-matter interaction and decoherence mechanisms in solid-state quant…
Operating a bistable qubit
Fabrizio Berritta, Jan A. Krzywda, Tom Dvir +4
Parasitic two-level-system (TLS) defects limit the stability and performance of solid-state quantum processors. Their interaction with a qubit can cause discrete, stochastic shifts…
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…
Full Shapiro spectroscopy of current-phase relationships
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…
