Enabling the quantum internet at Qblox

[Elías Portolés @EliasPortoles]

Our paper "A tunable monolithic SQUID in twisted bilayer graphene" has been published in @NatureNano.
The work was carried out with @fkdevries1, @rindstartar and the rest of the team in the Ensslin group, check it out!

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!

The 2022 edition of the @NCCR_QSIT Junior Meeting took place a couple of weeks ago, here are some pictures of the event! Soon more to come on the QSIT website.

The spin relaxation time T1 in graphene quantum dots is shown to be on the order of tens of milliseconds, demonstrating the great potential of spin qubits in this novel material. @ETH_physics @QuESTech_H2020 @fkdevries1

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!

Ensslin group reunion at the March Meeting 2022 in Chicago! I presented today our work on a tunable monolithic SQUID in twisted bilayer graphene. Thanks @fkdevries1 and #Qblox for the beanies!

[Physical Review Letters @PhysRevLett]

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

[Elías Portolés @EliasPortoles]

Our latest work, "A Tunable Monolithic SQUID in Twisted Bilayer Graphene" is now on the #ArXiv! Together with @fkdevries1 and the rest of the team, we present the first Superconducting QUantum Interference Device in magic-angle graphene.

Great presentation by Giulia Zheng on the Fabry Perot oscillations in our twisted double bilayer graphene device. @GrapheneConf

[Sense Jan vd Molen @sensemolen]

Beautiful presentation by Chuyao Tong on Pauli spin and valley blockade. Great results, elegant physics and a very well delivered talk. (Ensslin group) @GrapheneConf

@EliasPortoles presenting our work on quantum dots in twisted graphene in Grenoble. It is great to attend an in person conference again. @GrapheneConf

[Fokko de Vries @fkdevries1]

The graphene quantum dots in our lab show the Kondo effect and intrinsic spin-orbit coupling. Read more about it in Nature Communications:
