Abstract

Section titled ā€œAbstractā€

Nitrogen-vacancy centers in diamond allow for coherent spin state\nmanipulation at room temperature, which could bring dramatic advances to\nnanoscale sensing and quantum information technology. We introduce a novel\nmethod for the optical measurement of the spin contrast in dense\nnitrogen-vacancy (NV) ensembles. This method brings a new insight into the\ninterplay between the spin contrast and fluorescence lifetime. We show that for\nimproving the spin readout sensitivity in NV ensembles, one should aim at\nmodifying the far field radiation pattern rather than enhancing the emission\nrate.\n
