Abstract: Quantum measurements has practical applications and four areas that stand out as the most likely applications: optical sensors, optical communication, spatial effects and imaging, and interferometric detectors for gravitational waves. This chapter discusses the standard quantum limits that apply to coherent states and ways to overcome them. It also discusses a different class of applications based on quantum information concepts. An optical sensor is a device that monitors a property and translates a change of this property into an optical signal. The chapter then discusses a more general approach that finds the ultimate precision limit for any detection strategy. Optical communication has been one of the motivations for the development of quantum optics technology. More applications will emerge from multiple squeezed modes and the generation of beams of entangled light. The simplest case is a pair of entangled beams from two squeezed beams, followed by beams with high-dimensional quantum correlations and generalized version of entanglement.
