Using Andreev bound states and spin to remove domain walls in a Kitaev chain
Wietze D. Huisman, Sebastiaan L. D. ten Haaf, Chun-Xiao Liu +6
Quantum dot-superconductor hybrids have been established as a suitable platform for realizing Kitaev chains hosting Majorana bound states. Implementing these structures in a qubit…
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…
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…
Spatial dependence of local density of states in semiconductor-superconductor hybrids
Qingzhen Wang, Yining Zhang, Saurabh Karwal +1
Majorana bound states are expected to appear in one-dimensional semiconductor-superconductor hybrid systems, provided they are homogenous enough to host a global topological phase.…
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…
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…
Crossed Andreev reflection and elastic co-tunneling in a three-site Kitaev chain nanowire device
Alberto Bordin, Xiang Li, David van Driel +7
The formation of a topological superconducting phase in a quantum-dot-based Kitaev chain requires nearest neighbor crossed Andreev reflection and elastic co-tunneling. Here we repo…
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…
InSbAs two-dimensional electron gases as a platform for topological superconductivity
Christian M. Moehle, Chung Ting Ke, Qingzhen Wang +10
Topological superconductivity can be engineered in semiconductors with strong spin-orbit interaction coupled to a superconductor. Experimental advances in this field have often bee…
