基于连通矩展开的量子模拟
Quantum simulations employing connected moments expansions
摘要：
量子计算（QC）的进一步发展取决于启用多体模型，这些模型避免了深电路和CNOT门的过度使用。为此，我们开发了一种QC方法，采用有限阶连接矩展开（CMX）和负担得起的初始状态准备程序。我们证明了我们的方法的性能，采用几个量子变体的CMX通过经典的H2分子势能面和安德森模型的仿真与广泛的相关强度。结果表明，我们的方法是强大的和灵活的。即使在解离和强相关极限下，也可以保持与精确解的良好一致。
英文摘要：
Further advancement of quantum computing (QC) is contingent on enabling many-body models that avoid deep circuits and excessive use of CNOT gates. To this end, we develop a QC approach employing finite-order connected moment expansions (CMX) and affordable procedures for initial state preparation. We demonstrate the performance of our approach employing several quantum variants of CMX through the classical emulations on the H2 molecule potential energy surface and the Anderson model with a broad range of correlation strength. The results show that our approach is robust and flexible. Good agreements with exact solutions can be maintained even at the dissociation and strong correlation limits.
