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
A great number of PhD positions in the field of quantum science and quantum technologies has been funded by the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie program. The nanoelectronics group was granted one position in
The group had the pleasure to visit the lab of Prof. Dr. Michel Calame today (5. April 2019) at EMPA Thanks a lot Michel for this interesting day!
Our paper entitled “New Generation of Moiré Superlattices in Doubly Aligned hBN/ Graphene/hBN Heterostructures” appeared in Nano Letters. Two incommensurate lattices in contact generate a Moiré superlattice. This happens for the pair hBN-G (hexagonal boron nitride-graphene). Take encapsulated graphene hBN-G-hBN.
Wonderful weather: blue sky, sunshine and snow! We stayed overnight in the Berghotel Bischofalp We can highly recommend it. We all enjoyed the two days including Joost, who had to suffer a bit (see his right hand on the picture below):
