Abstract
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 quantumsimulators. 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.
