论文摘要
核是一种典型的多体量子系统。经典计算机中核系统的完整计算远远超出了当前的古典计算机的能力。随着硬件的快速开发，在核物理学中使用量子计算机的前景正在关闭。在这里，我们报告了一个完整的量子包，QCSH，用于在量子计算机中求解核壳模型。 QCSH使用量子计算的单位形式主义的线性组合，并在量子计算机中执行所有计算。 QCSH的基本大门的量子资源的复杂性都是多项式到核大小的。 QCSH已经可以在短期内提供有意义的结果。作为示例，十二光核的约束能量，$^{2} $ h，$^{3} $ h，$^{3} $ he，$^{4} $ he，$^{6} $ li，$^{7} $^{17} $ o，$^{23} $ na和$^{40} $ ca是在经典量子模拟器中使用QCSH计算的。 Deuteron的结合能已经在超导量子计算设备上使用QCSH进行了实验研究。 QCSH不仅可以在近期量子设备中工作，而且在将来的大型量子计算机中工作。随着量子设备的开发，核系统构成了证明实用量子优势的另一个有前途的领域。
Nucleus is a typical many-body quantum system. Full calculation of a nuclear system in a classical computer is far beyond the capacity of current classical computers. With fast development of hardware, the prospect of using quantum computers in nuclear physics is closing. Here, we report a full quantum package, QCSH, for solving nuclear shell-model in a quantum computer. QCSH uses the linear combination of unitaries formalism of quantum computing, and performs all calculations in a quantum computer. The complexities of qubit resource, number of basic gates of QCSH, are both polynomial to the nuclear size. QCSH can already provide meaningful results in the near term. As examples, the binding energies of twelve light nuclei, $^{2}$H, $^{3}$H, $^{3}$He, $^{4}$He, $^{6}$Li, $^{7}$Li, $^{12}$C, $^{14}$N, $^{16}$O, $^{17}$O, $^{23}$Na and $^{40}$Ca are calculated using QCSH in a classical quantum emulator. The binding energy of Deuteron has already been experimentally studied using QCSH on a superconducting quantum computing device. QCSH not only works in near-term quantum devices, but also in future large-scale quantum computers. With the development of quantum devices, nuclear system constitutes another promising area for demonstrating practical quantum advantage.
