The analogy between quantum chemistry and light-front quantum field theory, first noted by Wilson, serves as motivation to develop light-front quantum simulation of quantum field theory. We demonstrate how calculations of hadron structure can be performed on noisy intermediate-scale quantum devices within the basis light-front quantization (BLFQ) framework. Within BLFQ, relativistic quantum field theories take a form that permits direct application of methods for digital quantum simulation of quantum chemistry, which can be readily scaled into the quantum advantage regime. We calculate the light-front wave functions of pions using an effective light-front Hamiltonian in a basis representation on a current quantum processor. We use the variational quantum eigensolver to find the ground-state energy and the corresponding wave function, which is subsequently used to calculate pion mass radius, decay constant, elastic form factor, and charge radius.

使用基础光前量子化在嘈杂的中尺度量子设备上模拟强子物理学

量子化学和光前量子场论之间的类比，首先由威尔逊指出，是开发量子场论光前量子模拟的动力。我们展示了如何在基础光前量子化 (BLFQ) 框架内在嘈杂的中尺度量子设备上执行强子结构的计算。在 BLFQ 中，相对论量子场论采用的形式允许直接应用量子化学的数字量子模拟方法，可以很容易地将其扩展到量子优势体系中。我们在当前量子处理器的基础表示中使用有效的光前哈密顿量来计算π介子的光前波函数。我们使用变分量子本征求解器来找到基态能量和相应的波函数，
