Nitrogen vacancy (NV) centres in diamond exhibit remarkable features, comparable to those of a trapped atom albeit being a genuine solid-state system. Intense research in recent years has sought to exploit these exceptional attributes for various applications ranging from quantum information to neurosciences. We report the experimental observation of the quantum Zeno effect in the radio frequency transition between two NV⁻ ground state spin levels (a spin 1 system) in nanodiamond using optical read-out techniques.
