Magnetic field independent sub-gap states in hybrid Rashba nanowires Most reports on the highly visible topic of Majorana Fermions in solid state systems are based on the observation of magnetic field independent transport resonances at zero bias, so-called zero-bias peaks.
One-dimensional edge transport in few-layer WTe2 In 2016 the Nobel Prize in Physics was given to three theorists who introduced a new state of matter, topological matter. A subclass is defined by topological insulators (TIs), which are crystals that are
Physicists of the Budapest University of Technology and Economics (BME) and the University of Basel discovered a surprising result on the extension of Yu-Shiba-Rusinov states. Their joint studies appeared in Nature Communications. Recently several promising novel qubit concepts have been
Our paper entitled “Mobility Enhancement in Graphene by in situ Reduction of Random Strain Fluctuations” appeared in Phys. Rev. Lett. Bumps on a road slow down our pace, so do corrugations in graphene to travelling electrons. By flattening the corrugations
Last week Thursday and Friday we were exploring “one of the most famous ski resorts in Switzerland: We had a good start with a special bus only for us! Martin, well done! The plan was
Project TOPSQUAD (Topologically Protected and Scalable Quantum Bits) started with a kick-off meeting at the University of Twente Tursday and Friday 13th and 14th of Febr. 2020. The project aims to engineer qubits into the standard IC material Silicon and
In this new publication, entitled: Highly symmetric and tunable tunnel couplings in InAs/InP nanowire heterostructure quantum dots Frederick and co-worker show that built-in quantum dots (QD) are very versatile for high resolution tunneling spectroscopy, since the tunnel coupling strength G1 and G2 can be
Lujun succeessfully defended his thesis on Tuesday Jan. 7th. Congratulations! Happy Lujun. Note, the magnified picture of his hat, shown on the bootm image! We are grateful to the two external reviewers: Prof. Dr. Christoph Stampfer (RWTH
FET-OPEN grant for topological states in germanium nanowires Limited scalability and the high sensitivity of qubits as building blocks for the quantum computer are still in the way of the ‘super computer’s’ big breakthrough. Researchers of the University of Twente,
The plan was to hike in the Swiss alps in the Greina area and stay overnight in the SAC hut Terrhütte. Due to the bad weather forcast, Martin, Christian and Frederick decided one day before to change to Ticino to
