Probing ground-state degeneracies of a strongly interacting Fermi-Hubbard model with superconducting correlations
Sebastiaan L. D. ten Haaf, Sebastian Miles, Qingzhen Wang +6
The Fermi-Hubbard model and its rich phase diagram naturally emerges as a description for a wide range of electronic systems. Recent advances in semiconductor-superconductor hybrid…
Gate reflectometry in a minimal Kitaev chain device
Yining Zhang, Ivan Kulesh, Sebastiaan L. D. ten Haaf +5
Hybrid quantum dot (QD)-superconductor system can be used to realize Majorana zero modes in artificial Kitaev chains. These chains provide a promising platform for the realization…
A flux-controlled two-site Kitaev chain
Ivan Kulesh, Sebastiaan L. D. ten Haaf, Qingzhen Wang +8
In semiconducting-superconducting hybrid devices, Andreev bound states (ABSs) can mediate the coupling between quantum dots (QDs), allowing for the realisation of artificial Kitaev…
Observation of edge and bulk states in a three-site Kitaev chain
Sebastiaan L. D. ten Haaf, Yining Zhang, Qingzhen Wang +10
A chain of quantum dots (QDs) in semiconductor-superconductor hybrid systems can form an artificial Kitaev chain hosting Majorana bound states (MBSs). These zero-energy states are…
Flux-tunable Josephson Effect in a Four-Terminal Junction
Christian G. Prosko, Wietze D. Huisman, Ivan Kulesh +4
We study a phase-tunable four-terminal Josephson junction formed in an InSbAs two-dimensional electron gas proximitized by aluminum. By embedding the two pairs of junction terminal…
Flux-Tunable Hybridization in a Double Quantum Dot Interferometer
Christian G. Prosko, Ivan Kulesh, Michael Chan +6
A single electron shared between two levels threaded by a magnetic flux is an irreducibly simple quantum system in which interference is predicted to occur. We demonstrate tuning o…
Quantum capacitance of a superconducting subgap state in an electrostatically floating dot-island
Filip K. Malinowski, R. K. Rupesh, Luka Pavešić +10
We study a hybrid device defined in an InAs nanowire with an epitaxial Al shell that consists of a quantum dot in contact with a superconducting island. The device is electrically…
Controllable Single Cooper Pair Splitting in Hybrid Quantum Dot Systems
Damaz de Jong, Christian G. Prosko, Lin Han +4
Cooper pair splitters hold utility as a platform for investigating the entanglement of electrons in Cooper pairs, but probing splitters with voltage-biased Ohmic contacts prevents…
Variable and orbital-dependent spin-orbit field orientations in a InSb double quantum dot characterized via dispersive gate sensing
Lin Han, Michael Chan, Damaz de Jong +7
Utilizing dispersive gate sensing (DGS), we investigate the spin-orbit field () orientation in a many-electron double quantum dot (DQD) defined in an InSb nanowire…
Radio-frequency C-V measurements with sub-attofarad sensitivity
Filip K. Malinowski, Lin Han, Damaz de Jong +9
We demonstrate the use of radio-frequency (rf) resonators to measure the capacitance of nano-scale semiconducting devices in field-effect transistor configurations. The rf resonato…
Rapid microwave-only characterization and readout of quantum dots using multiplexed gigahertz-frequency resonators
Damaz de Jong, Christian Prosko, Daan M. A. Waardenburg +6
Superconducting resonators enable fast characterization and readout of mesoscopic quantum devices. Finding ways to perform measurements of interest on such devices using resonators…
Revealing charge-tunneling processes between a quantum dot and a superconducting island through gate sensing
Jasper van Veen, Damaz de Jong, Lin Han +5
We report direct detection of charge-tunneling between a quantum dot and a superconducting island through radio-frequency gate sensing. We are able to resolve spin-dependent quasip…
