Recent years have witnessed a growing interest in understating the limitations imposed by quantum noise in precision measurements and devising techniques to reduce it. The attention is currently turning to the simultaneously estimation of several parameters of interest, driven by its promising potential across a wide range of sensing applications as well as fueled by experimental progress in various optical and atomic platforms. Here, we provide a comprehensive overview of key research directions in multiparameter quantum sensing and metrology, highlighting both opportunities and challenges. We introduce the basic framework, discuss ultimate sensitivity bounds, optimal measurement strategies, and the role of quantum incompatibility, showing important differences with respect to single-parameter estimation. Additionally, we discuss emerging experimental implementations in distributed quantum sensing, including cutting-edge optimization techniques. This review aims to bridge the gap between theory and experiments, paving the way for the next-generation of quantum sensors and their integration with other quantum technologies.

Hierarchy of saturation conditions for multiparameter quantum metrology bounds
Commuting parameter-encoding generators do not guarantee saturability of the quantum Cramér-Rao bound for mixed probe states, and the hierarchy of commutativity conditions has strict gaps.

Quantum sensing of displacements with stabilized GKP states
A stabilized GKP qunaught state used with small-big-small feedback estimates two quadrature displacements nearly at the quantum Cramer-Rao bound and beats Gaussian sensing limits under realistic noise.
