Guerin %J Physics %D 2013 %I arXiv %R 10.1103/PhysRevLett.111.050404 %X Considering the problem of the control of a two-state quantum system by an external field, we establish a general and versatile method that allows the derivation of smooth pulses, suitable for ultrafast applications, that feature the properties of high-fidelity, robustness, and low area. Such shaped pulses can be viewed as a single-shot generalization of the composite pulse technique with a time-dependent phase. %U http://arxiv.org/abs/1304.4016v2
