论文摘要
轻孔分布幅度（LCDA）是量子染色体学（QCD）独家高能过程的理论预测的必要非扰动量。我们通过在（1+1） - 二维Nambu-Jona-Jona-lasinio（NJL）模拟经典硬件上的LCDA模拟LCDA来证明在量子计算机上计算LCDA的前景。来自量子算法的经典模拟与精确对角线化的结果之间的一致性证明了所提出的量子算法。我们发现NJL模型中所得的LCDA展示了与QCD获得的LCDA共享的特征。
Light-cone distribution amplitudes (LCDAs) are essential nonperturbative quantities for theoretical predictions of exclusive high-energy processes in quantum chromodynamics (QCD). We demonstrate the prospect of calculating LCDAs on a quantum computer by applying a recently proposed quantum algorithm, with staggered fermions, to the simulation of the LCDA in the (1+1)-dimensional Nambu-Jona-Lasinio (NJL) model on classical hardware. The agreement between the result from the classical simulation of the quantum algorithm and that from exact diagonalization justifies the proposed quantum algorithm. We find that the resulting LCDA in the NJL model exhibits features shared with the LCDAs obtained from QCD.
