我们报告了首次在量子硬件上实现散射观测量实时估计器(RESOs)。物理模型是一维格点理论,描述具有单接触相互作用的非相对论性自旋-1/2费米子。研究的格点尺寸最大为$N_x=54$个格点,时间步长最多为$20$步。时空关联函数在IBM的量子计算机上计算,使用了$109$个量子比特,施加了$10,806$个CZ门,达到两量子比特门深度$246$。我们展示了如何从这些关联函数研究束缚态并提取散射振幅。
英文摘要
We report the first quantum-hardware implementation of Real-time Estimators for Scattering Observables (RESOs). The physical model is a one-dimensional lattice theory of non-relativistic spin-1/2 fermions with a single contact interaction. The lattice sizes studied are up to $N_x=54$ lattice sites and up to $20$ time steps. Spacetime correlation functions were computed on IBM's quantum computers, using $109$ qubits with $10,806$ CZ gates applied, reaching a two-qubit gate depth of $246$. We demonstrate how to study bound states and extract scattering amplitudes from these correlation functions.
