“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 …

Quantum Fisher information matrix (QFIM) is a core concept in theoretical quantum
metrology due to the significant importance of quantum Cramér–Rao bound in quantum …

Quantum metrology is one of the most promising applications of quantum technologies. The
aim of this research field is the estimation of unknown parameters exploiting quantum …

Quantum metrology holds the promise of an early practical application of quantum
technologies, in which measurements of physical quantities can be made with much greater …

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 purpose of quantum technologies is to explore how quantum effects can improve on
existing solutions for the treatment of information. Quantum photonics sensing holds great …

This review aims at gathering the most relevant quantum multi-parameter estimation
methods that go beyond the direct use of the quantum Fisher information concept. We …

We study multiparameter sensing of two-dimensional (2D) and three-dimensional (3D)
vector fields within the Bayesian framework for SU (2) quantum interferometry. We establish …

Rapid experimental progress has recently allowed the use of light to prepare macroscopic
mechanical objects into nearly pure quantum states. This research field of quantum …

Quantum metrology has been studied for a wide range of systems with time-independent
Hamiltonians. For systems with time-dependent Hamiltonians, however, due to the …
