摘　　要：The geometric phase has the intrinsic property of being resistant to some types of local noises as it only depends on global properties of the evolution path.Meanwhile,the non-Abelian geometric phase is in the matrix form,and thus can naturally be used to implement high performance quantum gates,i.e.,the so-called holonomic quantum computation.This article reviews recent advances in nonadiabatic holonomic quantum computation,and focuses on various optimal control approaches that can improve the gate performance,in terms of gate fidelity and robustness.Besides,we also pay special attention to its possible physical realizations and some concrete examples of experimental realizations.Finally,with all these efforts,within state-of-the-art technology,the performance of the implemented holonomic quantum gates can outperform the conventional dynamical ones,under certain conditions.
