论文摘要
量规理论的量子模拟需要有效的数字化。基于离散子组的方案以系统错误为代价使用量较少。我们通过得出单个plaquette动作来对这种方法进行系统化,以通过整合场外波动来近似一般的连续量规组。这提供了有关这些近似值的有效性以及如何改善它们的有效性的洞察力。我们伴随着该计划,以$ su(3)$的最大离散子组的模拟为第三订单。
Efficient digitization is required for quantum simulations of gauge theories. Schemes based on discrete subgroups use fewer qubits at the cost of systematic errors. We systematize this approach by deriving a single plaquette action for approximating general continuous gauge groups through integrating out field fluctuations. This provides insight into the effectiveness of these approximations, and how they could be improved. We accompany the scheme by simulations of pure gauge over the largest discrete subgroup of $SU(3)$ up to the third order.
