“Quantum sensing” describes the use of a quantum system, quantum properties, or quantum
phenomena to perform a measurement of a physical quantity. Historical examples of …

Direct measurements of spin fluctuations are becoming the mainstream approach for studies
of complex condensed matter, molecular, nuclear, and atomic systems. This review covers …

Application of nuclear magnetic resonance (NMR) spectroscopy to nanoscale samples has
remained an elusive goal, achieved only with great experimental effort at subkelvin …

Extension of nuclear magnetic resonance (NMR) to nanoscale samples has been a
longstanding challenge because of the insensitivity of conventional detection methods. We …

We describe a scanning device where a single spin is used as an ultrasensitive, nanoscale
magnetic field sensor. As this “probe spin” we consider a single nitrogen-vacancy defect …

We have combined ultrasensitive magnetic resonance force microscopy (MRFM) with 3D
image reconstruction to achieve magnetic resonance imaging (MRI) with resolution< 10 nm …

We present nanoscale nuclear magnetic resonance (NMR) measurements performed with
nitrogen-vacancy (NV) centers located down to about 2 nm from the diamond surface. NV …

We review recent efforts to detect small numbers of nuclear spins using magnetic resonance
force microscopy. Magnetic resonance force microscopy (MRFM) is a scanning probe …

Experimental noise often contains information about the interactions of a system with its
environment, but establishing a relation between the measured time fluctuations and the …

We discuss multipulse magnetometry that exploits all three magnetic sublevels of the S= 1
nitrogen-vacancy center in diamond to achieve enhanced magnetic field sensitivity. Based …
