Query: Leakage suppression by ultrafast pulse shaping   We consider the leakage suppression problem of a three-level system in which
the first two levels are the qubit system and the third, weakly-coupled to the
second, is the leakage state. We show that phase- and amplitude-controlled two
(three) pulses are sufficient for arbitrary qubit controls from the ground (an
arbitrary) initial state, with leakage suppressed up to the first order of
perturbation without additional pulse-area cost. A proof-of-principle
experiment was performed with shaped femtosecond optical pulses and atomic
rubidium showing a good agreement with the theory.
