One-step generation of multipartite entanglement among nitrogen-vacancy center ensembles
One-step generation multipartite entanglement nitrogen-vacancy center ensembles
2016/1/22
We describe a one-step, deterministic and scalable scheme for creating macroscopic arbitrary entangled coherent states (ECSs) of separate nitrogen-vacancy center ensembles (NVEs) that couple to a supe...

2016/1/22
We present a proposal to realize the quantum Zeno effect (QZE) and quantum Zeno-like effect (QZLE) in a proximal 13 C nuclear spin by controlling a proximal electron spin of a nitrogen vacancy (NV) c...
