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

The statistical error in any estimation can be reduced by repeating the measurement and
averaging the results. The central limit theorem implies that the reduction is proportional to …

The extraordinary sensitivity of plasmonic sensors is well-known in the optics and photonics
community. These sensors exploit simultaneously the enhancement and the localization of …

This book offers a concise review of quantum radar theory. Our approach is pedagogical,
making emphasis on the physics behind the operation of a hypothetical quantum radar. We …

Precise interferometric measurement is vital to many scientific and technological
applications. Using quantum entanglement allows interferometric sensitivity that surpasses …

We investigate the performance of entangled coherent states for quantum-enhanced phase
estimation. An exact analytical expression of quantum Fisher information is derived to show …

Over the past 20 years, bright sources of entangled photons have led to a renaissance in
quantum optical interferometry. Optical interferometry has been used to test the foundations …

Quantum Fisher information of a parameter characterizes the sensitivity of the state with
respect to changes of the parameter. In this article, we study the quantum Fisher information …

We find a phase-matching condition for enhancement of sensitivity in a Mach-Zehnder
interferometer illuminated by an arbitrary state in one input port and an odd (even) state in …

Phase precision in optimal two-channel quantum interferometry is studied in the limit of large
photon number N≫ 1, for losses occurring in either one or both channels. For losses in one …
