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…

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…
