Quantum simulation can beat current classical computers with minimally a few tens of qubits. Here we report an experimental demonstration that a small nuclear-magnetic-resonance quantum simulator is already able to simulate the dynamics of a prototype laser-driven isomerization reaction using engineered quantum control pulses. The experimental results agree well with classical simulations. We conclude that the quantum simulation of chemical reaction dynamics not computable on current classical computers is feasible in the near future.
量子模拟可以在至少几十个量子比特的情况下击败当前的经典计算机。在这里，我们报告了一个实验演示，即一个小型核磁共振量子模拟器已经能够使用工程量子控制脉冲来模拟原型激光驱动异构化反应的动力学。实验结果与经典模拟吻合较好。我们得出结论，在不久的将来，对于当前经典计算机不可计算的化学反应动力学的量子模拟是可行的。
