SUMMARY:Scalable and Parallel Quantum Sensing of Correlated Noise with
  Individual Nitrogen-Vacancy Centers in Diamond\, R. G. Herb Condensed
  Matter Seminar\, Shimon Kolkowitz\, Berkeley
DESCRIPTION:The nitrogen-vacancy (NV) center in diamond has been widel
 y adopted as a quantum sensor\, and is now even used in undergraduate 
 instructional labs as a model quantum system. However\, despite its ub
 iquity and popularity\, most work has been restricted to measurements 
 of one NV center at a time\, or to globally averaged measurements of e
 nsembles of many of NV centers. In this talk I will first introduce qu
 antum sensing with nitrogen-vacancy centers\, and will explain its bas
 ic principles and the emerging applications. I will then present our e
 xperimental demonstration of spatiotemporal magnetic field correlation
  measurements with pairs of NV centers\, including the ability to dist
 inguish between global and local noise sources\, and the capability to
  measure signals of interest using free precession times beyond the ap
 parent single NV coherence time in certain regimes. I will also presen
 t recent experimental results demonstrating entanglement-enhanced sens
 ing of magnetic field correlations at nanometer lengths scales using e
 ntangled pairs of NV centers. Finally\, I will present a new experimen
 tal platform we have developed for simultaneously manipulating and ind
 ependently measuring hundreds to thousands of single NV centers in par
 allel\, including the parallel measurement of many thousands of two-po
 int correlators.
