论文摘要
量子场理论的量子模拟为研究物质基本成分的性质提供了一种新的方法。我们基于相对论场理论的光式公式开发量子模拟算法。将解释在轻频坐标中量化系统的过程,以使用块对角线,每个块用一定的谐波分辨率K近似。我们在2+1d中分析了QCD理论。我们计算了Parton分布函数的类似物,这些理论中的介体复合颗粒(如Hadron)的广义Parton分布函数。将这种分析对量表数量缩放的依赖性与其他方案和常规计算进行了比较。轻型公式具有显着的优势。
Quantum simulation of quantum field theories offers a new way to investigate properties of the fundamental constituents of matter. We develop quantum simulation algorithms based on the light-front formulation of relativistic field theories. The process of quantizing the system in light-cone coordinates will be explained for a Hamiltonian formulation, which becomes block diagonal, each block approximating the Fock space with a certain harmonic resolution K. We analyze a QCD theory in 2+1D. We compute the analogue of parton distribution functions, the generalized parton distribution functions for mesonic composite particles, like hadrons, in these theories. The dependence of such analyses on the scaling of the number of qubits is compared with other schemes and conventional computations. There is a notable advantage to the light-front formulation.
