Although offering robustness to experimental imperfections, adiabatic processes are susceptible to decoherence due to their long evolution time. A general strategy termed "shortcuts to adiabaticity" (STA) aims to remedy this vulnerability by designing fast dynamics to reproduce the results of slow, adiabatic evolutions. Here, we implement a novel STA technique known as "superadiabatic transitionless driving" (SATD) to speed up stimulated Raman adiabatic passage (STIRAP) in a solid-state lambda ({\Lambda}) system. Utilizing optical transitions to a dissipative excited state in the nitrogen-vacancy (NV) center in diamond, we demonstrate the accelerated performance of different shortcut trajectories for population transfer and for the initialization and transfer of coherent superpositions. We reveal that SATD protocols exhibit robustness to dissipation and experimental uncertainty, and can be optimized when these effects are present. These results motivate STA as a promising tool for controlling open quantum systems comprising individual or hybrid nanomechanical, superconducting, and photonic elements in the solid state.Adiabatic processes are useful for quantum technologies but, despite their robustness to experimental imperfections, they remain susceptible to decoherence due to their long evolution time.

We reveal that SATD protocols exhibit robustness to dissipation and experimental uncertainty, and can be optimized when these effects are present. These results suggest that STA could be effective for controlling a variety of solid-state open quantum systems.</dcterms:abstract> <dc:contributor>Zhou, Brian B.</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2017-05-08T15:12:34Z</dc:date> <dc:contributor>Ribeiro, Hugo</dc:contributor> <dc:creator>Yale, Christopher G.</dc:creator> <dc:contributor>Jerger, Paul C.</dc:contributor> <dc:contributor>Awschalom, David D.</dc:contributor> <dcterms:title>Accelerated quantum control using superadiabatic dynamics in a solid-state lambda system</dcterms:title> <dc:creator>Auer, Adrian</dc:creator> <dc:contributor>Auer, Adrian</dc:contributor> <dc:creator>Baksic, Alexandre</dc:creator> <dcterms:issued>2017</dcterms:issued> <dc:creator>Heremans, F.
