Entropy spectroscopy of a bilayer graphene quantum dot
Christoph Adam, Hadrien Duprez, Natalie Lehmann +13
We measure the entropy change of charge transitions in an electrostatically defined quantum dot in bilayer graphene. Entropy provides insights into the equilibrium thermodynamic pr…

Spin-Valley Protected Kramers Pair in Bilayer Graphene
Artem O. Denisov, Veronika Reckova, Solenn Cances +11
The intrinsic valley degree of freedom makes bilayer graphene (BLG) a unique platform for semiconductor qubits. The single-carrier quantum dot (QD) ground state exhibits a two-fold…

Spin-valley locked excited states spectroscopy in a one-particle bilayer graphene quantum dot
Hadrien Duprez, Solenn Cances, Andraz Omahen +12
Current semiconductor qubits rely either on the spin or on the charge degree of freedom to encode quantum information. By contrast, in bilayer graphene the valley degree of freedom…
