论文摘要
脉冲成型设备准确生成量子最佳控制的能力是对量子技术开发的强大限制。我们提出并展示了一个系统的程序，以设计适合此类实验约束的强大数字控制过程。我们显示了该数字脉冲可以在多大程度上从其连续时间对应物获得。即使对于有限数量的脉冲参数，也可以达到显着的效率。我们通过实验在IBM量子计算机上实现了一个量子计算机的协议，在时间t = 382 ns中获得了最佳的稳健传输。
The ability of pulse-shaping devices to generate accurately quantum optimal control is a strong limitation to the development of quantum technologies. We propose and demonstrate a systematic procedure to design robust digital control processes adapted to such experimental constraints. We show to what extent this digital pulse can be obtained from its continuous-time counterpart. A remarkable efficiency can be achieved even for a limited number of pulse parameters. We experimentally implement the protocols on IBM quantum computers for a single qubit, obtaining an optimal robust transfer in a time T = 382 ns.
