  We have developed and implemented a new quantum molecular dynamics
approximation that allows fast and accurate simulations of dense plasmas from
cold to hot conditions. The method is based on a carefully designed
orbital-free implementation of density functional theory (DFT). The results for
hydrogen and aluminum are in very good agreement with Kohn-Sham (orbital-based)
DFT and path integral Monte Carlo (PIMC) for microscopic features such as the
electron density as well as equation of state. The present approach does not
scale with temperature and hence extends to higher temperatures than is
accessible in Kohn-Sham method and lower temperatures than is accessible by
PIMC, while being significantly less computationally expensive than either of
those two methods
