Probing charge noise in bilayer graphene quantum dots by Landau-Zener-Stückelberg-Majorana spectroscopy
Katrin Hecker, Samuel Möller, Tobias DeuÃen +6
Charge noise is an important factor limiting qubit coherence and relaxation in solid-state devices. In bilayer graphene (BLG) quantum dots, recently established as a promising plat…
Radio-frequency charge detection on graphene electron-hole double quantum dots
Katrin Hecker, Samuel Möller, Hubert Dulisch +10
High-fidelity detection of charge transitions in quantum dots (QDs) is a key ingredient in solid state quantum computation. We demonstrate high-bandwidth radio-frequency charge det…
Electric field tunable spin-orbit gap in a bilayer graphene/WSe quantum dot
Hubert Dulisch, David Emmerich, Eike Icking +7
We report on the investigation of proximity-induced spin-orbit coupling (SOC) in a heterostructure of bilayer graphene (BLG) and tungsten diselenide (WSe). A BLG quantum dot (Q…
The role of antisymmetric orbitals and electron-electron interactions on the two-particle spin and valley blockade in graphene double quantum dots
Samuel Möller, Luca Banszerus, Katrin Hecker +5
We report on an experimental study of spin and valley blockade in two-electron bilayer graphene (BLG) double quantum dots (DQDs) and explore the limits set by asymmetric orbitals a…
