Low-Frequency Charge Noise in Bilayer Graphene Quantum Dots
Jessica Richter, Max J. Ruckriegel, Jonas D. Gerber +12
Bilayer graphene (BLG) quantum dots (QDs) are a promising platform for semiconductor qubits. However, the low-frequency charge noise that may ultimately limit coherence has remaine…

Clara Galante-Agero, Christoph Adam, Artem O. Denisov +9
We report the realization of a gate-defined quantum point contact (QPC) in bilayer graphene proximitized by a single aluminum superconducting electrode. Superconducting correlation…
Non-equilibrium transport reveals energy level degeneracy
Artem O. Denisov, Christoph Adam, Hadrien Duprez +7
We demonstrate a method to determine energy level degeneracies using non-equilibrium electronic transport through voltage-biased quantum dots. We establish the general validity of…

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…

We implement circuit quantum electrodynamics (cQED) with quantum dots in bilayer graphene, a maturing material platform for semiconductor qubits that can host long-lived spin and v…
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…
