论文摘要
量子设备可以克服经典计算机在核结构功能研究和质子和核的Parton Wigner分布中的局限性。在本次演讲中，我们通过使用混合量子计算机在QCD的高能量重点极限进行核结构的函数讨论，通过在QCD路径积分中表达QCD路径积分簇作为量子机械路径积分中的fermion决定因素超过$ 0+1+1 $ 1 $ 1 $ dimensial-digensial-digensional fermeniational fermionic and-demensional of-demensional fermionic and Boctonic Worldine in Backgack Laguge emage eguge Fields中。我们最简单的示例计算结构函数的众所周知的偶极模型结果$ f_2 $在高能regge限制中是可行的，NISQ ERA技术使用很少的Qubits和浅电路。可以在范围内以复杂性并扩展该示例，以计算结构函数，散射幅度和QCD中的其他实时相关函数，例如，以描述夸克 - 胶合等单中夸克和胶子的非平衡运输。
Quantum devices may overcome limitations of classical computers in studies of nuclear structure functions and parton Wigner distributions of protons and nuclei. In this talk, we discuss a worldline approach to compute nuclear structure functions in the high energy Regge limit of QCD using a hybrid quantum computer, by expressing the fermion determinant in the QCD path integral as a quantum mechanical path integral over $0+1$-dimensional fermionic and bosonic world-lines in background gauge fields. Our simplest example of computing the well-known dipole model result for the structure function $F_2$ in the high energy Regge limit is feasible with NISQ era technology using few qubits and shallow circuits. This example can be scaled up in complexity and extended in scope to compute structure functions, scattering amplitudes and other real-time correlation functions in QCD, relevant for example to describe non-equilibrium transport of quarks and gluons in a Quark-Gluon-Plasma.
