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…
Phonon-limited valley life times in single-particle bilayer graphene quantum dots
Luca Banszerus, Katrin Hecker, Lin Wang +6
The valley degree of freedom in 2D semiconductors, such as gapped bilayer graphene (BLG) and transition metal dichalcogenides, is a promising carrier of quantum information in the…
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…
Gate-defined single-electron transistors in twisted bilayer graphene
Alexander Rothstein, Ammon Fischer, Anthony Achtermann +12
Twisted bilayer graphene (tBLG) near the magic angle is a unique platform where the combination of topology and strong correlations gives rise to exotic electronic phases. These ph…
