ABSTRACT
This chapter aims to provide an overview of experimental studies that are relevant to the development of various qubits in two-dimensional (2D) materials. It outlines how future work should pursue the development of various qubits in 2D materials. The chapter reviews a few relevant transport experiments performed on graphene single quantum dots fabricated on SiO2/Si substrates. Ideally, the charge and spin degrees of freedom of a single electron trapped in quantum dots (QDs) are nature’s candidates of qubits for use in quantum computing operations. 2D materials with a hexagonal lattice structure possess a valley of energy-momentum dispersion at the corner of the hexagonal Brillouin zone. The single-electron transport properties of graphene nanodevices fabricated on SiO2 and hexagonal boron nitride substrates were both reviewed. The chapter discusses the effect exerted by a magnetic field on the single-particle energy of QDs. Perpendicular magnetic fields strongly affect the component of the electron wave functions in QD, resulting in the Fock-Darwin spectrum.
