论文摘要
我们报告了将量子计算应用于重夸克光谱研究研究的首次演示。基于重型夸克和古董系统的康奈尔电位模型,我们展示了如何使用IBM云量子计算平台上的VQE方法来制定和解决此哈密顿问题。通过零噪声外推法校正了由于全局去极化噪声通道引起的误差,从而与期望值一致。我们还将计算扩展到无噪声量子模拟器上的激发态,相对于基态。
We report a first demonstration for the application of quantum computing to heavy quarkonium spectroscopy study. Based on a Cornell-potential model for the heavy quark and antiquark system, we show how this Hamiltonian problem can be formulated and solved with the VQE approach on the IBM cloud quantum computing platform. Errors due to a global depolarizing noise channel are corrected with a zero-noise extrapolation method, resulting in good agreement with the expected value. We also extend the calculation to excited states on a noiseless quantum simulator by orthogonalization with respect to the ground state.
