We present quasi-energies and Floquet states of excitons driven by terahertz (THz) electric .elds
in a single quantum dot using the Floquet theory. The eigenvalues are signi.cantly coupled to
truncated states, which correspond to the number of photons in the THz .eld. In particular, we
.nd that for N = 20 photons the energy dierence between quasi-energy ladders remains almost
constant up to strengths of the THz .elds with f < 16 in a single quantum dot. The photon
representation is needed with the larger number to accurately describe the single quantum dot
system as the intensity of the THz .eld is increased.
