由于其几何性质，完整量子计算对某些类型的控制误差是容错的。完整量子计算虽然早在十多年前就已提出，但其实验实现仍然是一个公开的挑战。在这封信中，我们报告的第一个实验演示的非绝热完整量子计算在液体NMR量子信息处理器。两个非对易的单量子比特完整门，绕x和z轴的旋转，以及两个量子比特完整CNOT门通过非线性地演化工作量子比特和辅助量子比特来实现。这些通用基本门在非绝热完整量子计算中的成功实现证明了这种量子计算范式的实验可行性。
Because of 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 Letter, we report the first experimental demonstration of nonadiabatic holonomic quantum computation in a liquid NMR quantum information processor. Two noncommuting one-qubit holonomic gates, rotations about x and z axes, and the two-qubit holonomic CNOT gate are realized by evolving the work qubits and an ancillary qubit nonadiabatically. The successful realizations of these universal elementary gates in nonadiabatic holonomic quantum computation demonstrates the experimental feasibility of this quantum computing paradigm.
