提出了一种鲁棒、快速的光学超偏振原理，并用NV中心进行了实验验证。动态核极化（DNP）是利用电子向核自旋的极化转移来实现核超极化的一项重要技术。将高效DNP与光极化氮空位（NV）中心相结合，为新型技术应用提供了有希望的机会，包括纳米级液体核磁共振波谱，超极化纳米金刚石作为磁共振成像造影剂，以及基于核自旋的金刚石量子模拟器的初始化。然而，目前没有一种极化转移的实现同时具有鲁棒性和足够的效率，这使得其应用的实现极具挑战性。引入了利用哈密顿工程系统设计极化序列的概念，得到了鲁棒、快速的极化序列。我们从理论上推导出序列，并通过实验证明，即使在存在控制误差的情况下，它们也能够从金刚石的光偏振NV中心有效地极化转移到周围的13C核自旋槽，使上述新应用成为可能。
A robust and fast principle of optical hyperpolarization is proposed and demonstrated by using NV centers experimentally. Dynamic nuclear polarization (DNP) is an important technique that uses polarization transfer from electron to nuclear spins to achieve nuclear hyperpolarization. Combining efficient DNP with optically polarized nitrogen-vacancy (NV) centers offers promising opportunities for novel technological applications, including nanoscale nuclear magnetic resonance spectroscopy of liquids, hyperpolarized nanodiamonds as magnetic resonance imaging contrast agents, and the initialization of nuclear spin–based diamond quantum simulators. However, none of the current realizations of polarization transfer are simultaneously robust and sufficiently efficient, making the realization of the applications extremely challenging. We introduce the concept of systematically designing polarization sequences by Hamiltonian engineering, resulting in polarization sequences that are robust and fast. We theoretically derive sequences and experimentally demonstrate that they are capable of efficient polarization transfer from optically polarized NV centers in diamond to the surrounding 13C nuclear spin bath even in the presence of control errors, making the abovementioned novel applications possible.
