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 quantum dot in germanium proximitized by a superconductor
Lazar Lakic, William I. L. Lawrie, David van Driel +6
Planar germanium quantum wells have recently been shown to host hard-gapped superconductivity. Additionally, quantum dot spin qubits in germanium are well-suited for quantum inform…
Signatures of Majorana protection in a three-site Kitaev chain
Alberto Bordin, Chun-Xiao Liu, Tom Dvir +14
Majorana zero modes (MZMs) are non-Abelian excitations predicted to emerge at the edges of topological superconductors. One proposal for realizing a topological superconductor in o…
Supercurrent through an Andreev trimer
Alberto Bordin, Florian J. Bennebroek Evertsz', Gorm O. Steffensen +8
Detection and control of Andreev Bound States (ABSs) localized at semiconductor-superconductor interfaces are essential for their use in quantum applications. Here we investigate t…
Robust poor man's Majorana zero modes using Yu-Shiba-Rusinov states
Francesco Zatelli, David van Driel, Di Xu +14
The recent realization of a two-site Kitaev chain featuring "poor man's Majorana" states demonstrates a path forward in the field of topological superconductivity. Harnessing the p…
Charge sensing the parity of an Andreev molecule
David van Driel, Bart Roovers, Francesco Zatelli +10
The proximity effect of superconductivity on confined states in semiconductors gives rise to various bound states such as Andreev bound states (ABSs), Andreev molecules and Majoran…
Gate-tunable Superconductivity in Hybrid InSb-Pb Nanowires
Yan Chen, David van Driel, Charalampos Lampadaris +7
We present a report on hybrid InSb-Pb nanowires that combine high spin-orbit coupling with a high critical field and a large superconducting gap. Material characterization indicate…
Kitaev chain in an alternating quantum dot-Andreev bound state array
Sebastian Miles, David van Driel, Michael Wimmer +1
We propose to implement a Kitaev chain based on an array of alternating normal and superconductor hybrid quantum dots embedded in semiconductors. In particular, the orbitals in the…
Adversarial Hamiltonian learning of quantum dots in a minimal Kitaev chain
Rouven Koch, David van Driel, Alberto Bordin +2
Determining Hamiltonian parameters from noisy experimental measurements is a key task for the control of experimental quantum systems. An experimental platform that recently emerge…
Spin-filtered measurements of Andreev bound states
David van Driel, Guanzhong Wang, Alberto Bordin +9
A semiconductor nanowire brought in proximity to a superconductor can form discrete, particle-hole symmetric states, known as Andreev bound states (ABSs). An ABS can be found in it…
Controlled crossed Andreev reflection and elastic co-tunneling mediated by Andreev bound states
Alberto Bordin, Guanzhong Wang, Chun-Xiao Liu +12
A short superconducting segment can couple attached quantum dots via elastic co-tunneling (ECT) and crossed Andreev reflection (CAR). Such coupled quantum dots can host Majorana bo…
Electrostatic control of the proximity effect in the bulk of semiconductor-superconductor hybrids
N. van Loo, G. P. Mazur, T. Dvir +11
The proximity effect in semiconductor-superconductor nanowires is expected to generate an induced gap in the semiconductor. The magnitude of this induced gap, together with the sem…
Realization of a minimal Kitaev chain in coupled quantum dots
Tom Dvir, Guanzhong Wang, Nick van Loo +14
Majorana bound states constitute one of the simplest examples of emergent non-Abelian excitations in condensed matter physics. A toy model proposed by Kitaev shows that such states…

Ji-Yin Wang, Constantin Schrade, Vukan Levajac +13
We study a Cooper-pair transistor realized by two Josephson weak links that enclose a superconducting island in an InSb-Al hybrid nanowire. When the nanowire is subject to a magnet…
