论文摘要
在量子计算机上准备强耦合的粒子状态需要大量资源。在这项工作中,我们展示了如何将经典采样与投影操作员结合在一起来计算Minkowski矩阵元素,而无需在量子计算机上明确准备这些状态。我们为2+1d $ \ mathbb {z} _2 $带量子模拟器的小晶格晶格量规理论证明了这一点。
Preparing strongly-coupled particle states on quantum computers requires large resources. In this work, we show how classical sampling coupled with projection operators can be used to compute Minkowski matrix elements without explicitly preparing these states on the quantum computer. We demonstrate this for the 2+1d $\mathbb{Z}_2$ lattice gauge theory on small lattices with a quantum simulator.
