High Kinetic Inductance in Twisted Trilayer Graphene
Right to the start of the APS March meeting our paper appeared on arXiv. See: link
Strong Coupling between a Microwave Photon and a Singlet-Triplet Qubit
Jann Ungerer, Alessia Pally and collaborators have achieved strong coupling of a singlet-triplet qubit with a microwave photon. This work has now appeared in Nature Communications. They have employed crystal-face controlled nanowires that were grown at Lund university and provided
4e Supercurrent
We are thrilled to share our new paper entitled “Charge-4e supercurrent in a two-dimensional InAs-Al superconductor-semiconductor heterostructure” by Carlo Ciaccia. Supercurrent is carried by Cooper pairs having charge 2e. Accordingly, the second Josephson equation, which relates an AC supercurrent with
Andreev Bound State Fusion
Congrats to Christian Jünger and Andreas Baumgarter: the paper entitled Intermediate states in Andreev bound state fusion is finally out in Comm. Physics. The paper makes use of the best quantum dots (QDs) known to us. These QDs are grown
Electron entanglement for free
Entanglement has been at the centre of the 2022 Noble Prize in physics: NoblePrize22. Today, optical sources that generate pairs of entangled photons can routinely be realized and used in, for example, secure data communication. In contrast, it has turned out
Superconducting contacts to WTe2 via Pd diffusion
A Swiss-US-Japan collaboration involving the nanoelectronic group and the SNI NanoImaging lab at the University of Basel, the Swiss Federal Laboratories for Material Science and Technology (EMPA), the Department of Materials Science and Engineering and the Department of Physics at the
TWPA arrived at Basel
We are happy to announce that we have received the first Travelling-Wave Parametric Amplifier (TWPA) engineered and fabricated by Silent-Wave. Silent-Wave is a young start up from the Neél-Institute at Grenoble, France. The TWPA named Argo is their first commercial product.
Highlight hBN dielectrics
Yet another example of the high quality of h-BN dielectrics that have been engineered and provided by Kenji Watanabe and Takashi Taniguchi from the National Center for Materials Nanoarchitectonics, National Institute for Materials Science, 1-1 Namiki, 17 Tsukuba 305-0044, Japan.
Congratulation Roy: seminal paper out
Roy’s paper “Phase dependent microwave response of a graphene Josephson junction” is now out. See Phys. Rev. Research 4, 013198 (2022). Roy shows that one can obtain both the resistive the resistive loss and the critical current from GHz reflectometry measurements.
Winter 2022 group excursion
On the 3rd of March we went to Lenk in the Berneroberland to enjoy “airboarding”. Never done airboarding? Then, watch here: It was a lot of fun and the weather was great this time…! Thanks Roy and
