  An approach to electron correlation effects in atoms that uses quantum
trajectories is presented. A comparison with the exact quantum mechanical
results for 1D Helium atom shows that the major features of the correlated
ground state distribution and of the strong field ionization dynamics are
reproduced with quantum trajectories. The intra-atomic resonant transitions are
described accurately by a trajectory ensemble. The present approach reduces
significantly the computational time and it can be used for both bound and
ionizing electrons.
