标题： Triply-heavy/strange baryons with Cornell potential on a quantum computer

摘要： 我们展示了一种在量子计算机上计算三重重子的方法，采用了与 Gallimore 和 Liao 的早期类夸克偶素工作一致的康奈尔夸克模型。 这些重子是一些最有趣的尚未被探测到的标准模型粒子，因为它们关系到核力的短程（颜色）行为。 这里得到的能谱与早期工作的预测相兼容，我们的不确定性主要由传统的少体近似（变分基组的大小、质心反冲、参数估计等）主导，而不是由量子计算机（作为小型对角化器在此部署）的统计误差主导，至少在目前这种不成熟的少体近似中，这种统计误差可以忽略不计。 我们还用奇异夸克替换了其中一个或多个重夸克。 显示英文摘要

摘要： We present a computation of triply-heavy baryons on a quantum computer, employing the Cornell quark model in line with the earlier quarkonium work of Gallimore and Liao. These baryons are some of the most interesting Standard Model particles which have not yet been detected, as they bear on the short range (colour) behaviour of the nuclear force. The spectrum here obtained is compatible with predictions from earlier works, with our uncertainty dominated by traditional few-body approximations (size of the variational basis, center of mass recoil, parameter estimation...) and not by the statistical error from the quantum computer (deployed here as a small diagonalizer), which turns out to be negligible respect to the other sources of uncertainty, at least in the present unsophisticated few-body approximation. We have also substituted one or more heavy quarks for strange quarks.
