Quantun non demolition measurement and entanglement of multiple nuclear spins in diamond — •Gerald Waldherr, Sebastian Zaiser, Ya Wang, Philipp Neumann, and Jörg Wrachtrup — 3. Physikalisches Institut, Uni Stuttgart
QND measurement of a nitrogen nuclear spin associated with the nitrogen vacancy (NV) defect in diamond has previously been demonstrated [1]. Here, we will show that QND measurement of certain nearby 13C nuclear spins can also be performed. Additionally, we can use the interaction with the NV electron spin to entangle these nuclear spins with each other, to demonstrate basic quantum information processing tasks.
