Quantum Manipulation of Valleys in Bilayer Graphene: Theory and
Applications    [PDF]

G. Y. Wu, N. -Y. Lue, Y. -C. Chen

Quantum manipulation of valleys in bilayer graphene is investigated. We establish an effective Schrodinger model, and identify two key mechanisms for valley manipulation - band structure warping and generalized valley-orbit interaction. Specifically, we implement valley qubits / FETs in bilayer graphene, as prospective quantum devices to build valley-based quantum / classical information processing.
