  Monolayer transition metal dichalcogenides (TMDs) offer a novel
two-dimensional platform for semiconductor devices. One such application,
whereby the added low dimensional crystal physics (i.e. optical spin selection
rules) may prove TMDs a competitive candidate, are quantum dots as qubits. The
band structure of TMD monolayers offers a number of different degrees of
freedom and combinations thereof as potential qubit bases, primarily electron
spin, valley isospin and the combination of the two due to the strong spin
orbit coupling known as a Kramers qubit. Pure spin qubits in monolayer MoX$_2$
(where X=S or Se) can be achieved by energetically isolating a single valley
and tuning to a spin degenerate regime within that valley by a combination of a
sufficiently small quantum dot radius and large perpendicular magnetic field.
Within such a TMD spin qubit, we theoretically analyse single qubit rotations
induced by electric dipole spin resonance. We employ a rotating wave
approximation within a second order time dependent Schrieffer-Wolf effective
Hamiltonian to derive analytic expressions for the Rabi frequency of single
qubit oscilations, and optimise the mechanism or the parameters to show
oscilations up to $250\,{\rm MHz}$.
