规范理论的量子模拟需要高效的数字化。基于离散子群的方案以系统误差为代价使用更少的量子比特。通过积分外场涨落，我们得到了近似一般连续规范群的单一斑块作用量，从而使这一方法系统化。这提供了对这些近似的有效性的洞察，以及如何改进它们。伴随这一方案的是对最大三阶离散子群上的纯规范的模拟。
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 ofup to the third order.
