  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 current 2D technology. The results open up
new avenues for the field of physical implementation of qubits.
