摘要:

提出了一种有效的超玻恩-奥本海默分子能量计算的量子算法。我们的方法结合了量子全组态相互作用方法与核轨道加分子轨道(NOMO)方法。我们给出了算法的细节,并通过经典的仿真证明了它的性能。以氢分子的两种同位素(H $_2$,HT)为例,模拟计算了它们的最低无转动振动跃迁能.

英文摘要:

We present an efficient quantum algorithm for beyond-Born-Oppenheimer molecular energy computations. Our approach combines the quantum full configuration interaction method with the nuclear orbital plus molecular orbital (NOMO) method. We give the details of the algorithm and demonstrate its performance by classical simulations. Two isotopomers of the hydrogen molecule (H$_2$, HT) were chosen as representative examples and calculations of the lowest rotationless vibrational transition energies were simulated.
