在经典计算机上模拟量子系统是困难的，而量子计算机已被证明能够有效地执行此类模拟。我们报告了一个核磁共振实现模拟氢分子（H-2）在一个最小的基础上，以获得其基态能量。使用迭代核磁共振干涉仪测量相移，我们实现了45位的能量值估计。用不同构型的分子对绝热态制备的效率进行了实验测试。
It is difficult to simulate quantum systems on classical computers, while quantum computers have been proved to be able to efficiently perform such kinds of simulations. We report an NMR implementation simulating the hydrogen molecule (H-2) in a minimal basis to obtain its ground-state energy. Using an iterative NMR interferometer to measure the phase shift, we achieve a 45-bit estimation of the energy value. The efficiency of the adiabatic state preparation is also experimentally tested with various configurations of the same molecule.
