  We propose steady-state electron transport based on coherent transfer by
adiabatic passage (CTAP) in a linearly arranged triple quantum dot with leads
attached to the outer dots. Its main feature is repeated steering of single
electrons from the first dot to the last dot without relevant occupation of the
middle dot. The coupling to leads enables a steady-state current, whose shot
noise is significantly suppressed provided that the CTAP protocol performs
properly. This represents an indication for the direct transfer between
spatially separated dots and, thus, may resolve the problem of finding
experimental evidence for the non-occupation of the middle dot.
