Long-range phase coherence and phase patterns in hybrid Josephson junction arrays
Xi Wang, Asbjørn C. C. Drachmann, Candice Thomas +5
The coherence of superconductivity and its suppression near a quantum phase transition is governed by the interplay between local pairing and macroscopic phase coherence. Using sca…
Hybrid metal-semiconductor quantum dots in InAs as a platform for quantum simulation
Praveen Sriram, Connie L. Hsueh, Karna A. Morey +6
Arrays of hybrid metal-semiconductor islands offer a new approach to quantum simulation, with key advantages over arrays of conventional quantum dots. Because the metallic componen…
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…
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…
