Due to its geometric nature, holonomic quantum computation is fault-tolerant against certain types of control errors. Although proposed more than a decade ago, the experimental realization of holonomic quantum computation is still an open challenge. In this talk, the first experimental demonstration of nonadiabatic holonomic quantum computation performed in liquid NMR quantum information processors will be introduced. In the experiments, two non-commuting holonomic single-qubit gates, rotations about x- and z-axes, and the two-qubit holonomic control-NOT gate are realized with high fidelity by evolving the work qubits and an ancillary qubit nonadiabatically. The successful realization of these universal elementary gates in nonadiabatic quantum holonomic computing demonstrates the experimental feasibility and the fascinating feature of this fast and resilient quantum computing paradigm.
