Realistic quantum-enhanced interferometry

It is widely recognized that the use of nonclassical states of light allows one to overcome the shot-noise limit in precision measurements. The enhancement comes from exploiting inherently quantum features, such as entanglement, that are sensitive to decoherence. The outstanding challenge is to design quantum-enhanced measurement schemes that remain robust in realistic environments. We review our recent work in this direction for optical interferometry.
