@article{Lucatto2019ChargeQI, title={Charge qubit in van der Waals heterostructures}, author={B. Lucatto and Daniel S. Koda and F. Bechstedt and M. Marques and L. K. Teles}, journal={Physical Review B}, year={2019}, volume={100}, pages={121406} }

The use of spatial quantum superpositions of electron states in a gated vdW heterostructure as a charge qubit is presented. We theoretically demonstrate the concept for the ZrSe$_2$/SnSe$_2$ vdW heterostructure using rigorous ab initio calculations. In the proposed scheme, the quantum state is prepared by applying a vertical electric field, is manipulated by short field pulses, and is measured via electric currents. The qubit is robust, operational at high temperature, and compatible with the… Expand
