  Reaching a given target quantum state with high fidelity and fast operation
speed close to the quantum limit represents an important goal in quantum
information science. Here, we experimentally demonstrate superadiabatic quantum
driving to achieve population transfer in a three-level solid-state spin
system. Starting from traditional stimulated Raman adiabatic passage (STIRAP),
our approach implements superadiabatic corrections to the STIRAP Hamiltonians
with several paradigmatic pulse shapes. It requires no need of intense
microwave pulses or long transfer times and shows enhanced robustness over
pulse imperfections. These results might provide a useful tool for quantum
information processing and coherent manipulations of quantum systems.
