论文摘要
量子染色体动力学 - 夸克和胶子的理论 - 数十年来一直闻名，但尚未完全理解。最近的一个例子是对四夸克人的预测和实验发现，该发现开放了一个新的研究领域。至关重要的是，标准模型的许多未解决问题可以通过非扰动计算来完全解决。量子计算机可以解决已建立的QCD方法不可应用的问题，例如实时演变。我们通过在超导量子计算机上进行一维SU（3）量规理论，在一维SU（3）量规理论中执行Tetraquark和Pentaquark物理学的实时演变来探索这种可能性。我们的实验代表了涉及具有三个颜色自由度的夸克的第一个量子计算，即用QCD的量规组组。
Quantum chromodynamics - the theory of quarks and gluons - has been known for decades, but it is yet to be fully understood. A recent example is the prediction and experimental discovery of tetraquarks, that opened a new research field. Crucially, numerous unsolved questions of the standard model can exclusively be addressed by nonperturbative calculations. Quantum computers can solve problems for which well established QCD methods are inapplicable, such as real-time evolution. We take a key step in exploring this possibility by performing a real-time evolution of tetraquark and pentaquark physics in one-dimensional SU(3) gauge theory on a superconducting quantum computer. Our experiment represents a first quantum computation involving quarks with three colour degrees of freedom, i.e. with the gauge group of QCD.
