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…
Cross-Platform Autonomous Control of Minimal Kitaev Chains
David van Driel, Rouven Koch, Vincent P. M. Sietses +21
Contemporary quantum devices are reaching new limits in size and complexity, allowing for the experimental exploration of emergent quantum modes. However, this increased complexity…
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…
A two-site Kitaev chain in a two-dimensional electron gas
Sebastiaan L. D. ten Haaf, Qingzhen Wang, A. Mert Bozkurt +9
Artificial Kitaev chains can be used to engineer Majorana bound states (MBSs) in superconductor-semiconductor hybrids. In this work, we realize a two-site Kitaev chain in a two-dim…
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…
Triplet correlations in Cooper pair splitters realized in a two-dimensional electron gas
Qingzhen Wang, Sebastiaan L. D. ten Haaf, Ivan Kulesh +4
Cooper pairs occupy the ground state of superconductors and are typically composed of maximally entangled electrons with opposite spin. In order to study the spin and entanglement…
Stable quantum dots in an InSb two-dimensional electron gas
Ivan Kulesh, Chung Ting Ke, Candice Thomas +7
Indium antimonide (InSb) two-dimensional electron gases (2DEGs) have a unique combination of material properties: high electron mobility, strong spin-orbit interaction, large Landé…
