Europe bets on the quantum internet. The EC has selected the Quantum Internet Alliance to lead a seven year program to build an innovative Quantum Internet ecosystem in Europe. These days we are kicking-off in Delft. Stay tuned! #quantuminternet #innovation @QuantumFlagship

Paper published from Nano Letters! pubs.acs.org/doi/10.1021/acs… We present a “gate-defined electron interferometer,” a new member of the family of graphene devices. Using field-effect only, we formed a ring-shaped interferometer and observed beautiful quantum oscillations!

Gate-Defined Electron Interferometer in Bilayer Graphene

Abstract. We present an electron interferometer defined purely by electrostatic gating in an encapsulated bilayer graphene. This minimizes possible sample

arxiv.org/abs/2205.04081 We present a “gate-defined electron interferometer”, a new member of the family of graphene devices. Using field-effect only, our device lets the electron divide into two paths and meet again. This enables us to observe a beautiful quantum interference!

Oscillations in magnetotransport in twisted double bilayer graphene, and presumably other similar moiré materials, exhibit scattering between minivalleys that depends on both electron-phonon and electron-electron effects Letter: go.aps.org/3Hul9fm

A Tunable Monolithic SQUID in Twisted Bilayer Graphene

Magic-angle twisted bilayer graphene (MATBG) hosts a number of correlated states of matter that can be tuned by electrostatic doping. Superconductivity has drawn considerable attention and the...

Writing in @ScienceMagazine, the @ETH_physics group of Klaus Ensslin and Thomas Ihn, working with colleagues @UTPhysics & @NIMS_PR, report the observation that in twisted double-bilayer graphene two electrical conductors can team up to form an insulator. ethz.ch/en/news-and-events/e…
An insulator made of two conductors

An insulator made of two conductors

At ETH Zurich researchers have observed a new state of matter: in graphene layers twisted relative to each other, two electrical conductors team up to form an insulator.

The Ensslin group finished second in the yearly football tournament at @ETH_physics, loosing the final to @qudev 2-1. This was anyway the best team and supporters I could dream of! @fkdevries1 Congratulations to @AndreasAtETH for the win and thanks to #AMP for the organisation!

Great boat cruise on lake #Zurich, #Switzerland on the occasion of the 60th birthday of Klaus Ensslin, professor @ETH_physics @ETHQuantumCntr @ETH_en and director of the #quantum #science @NCCR_QSIT. It was great fun to meet current and past group members and invited guests!
