AI 中文摘要
我们报告了一种算法，用于从光前规范下量子化的第一性原理量子色动力学（QCD）哈密顿量计算碎裂函数，为数字量子计算机计算这些纵向喷注结构可观测量开辟了路径。在经典集群上模拟此类计算机的行为（考虑到实际量子计算机的庞大希尔伯特空间，其内存限制约为30个量子比特），我们运行了重夸克领头部分子碎裂为夸克偶素的演示，并将其与NRQCD计算进行基准测试。未来的量子计算机或许可与HL-LHC并行运行，将有充足机会提取任意部分子-强子组合。
英文摘要
We report on an algorithm to compute fragmentation functions from the first principles Quantum Chromodynamics (QCD) Hamiltonian quantized in Light-Front Gauge, opening a path for digital quantum computers to calculate these longitudinal jet-structure observables. Simulating the behaviour of such computers on a classical cluster (which is memory-limited to about 30 qubits, given the expansive Hilbert spaces of actual quantum computers), we run a demonstration of a heavy-quark leading parton fragmenting into quarkonium, which we benchmark against NRQCD computations. Future quantum computers, perhaps concurrently running with HL-LHC, would have ample opportunity to extract arbitrary parton-hadron combinations.
