Quantum metrology in many-body open systems

Quantum physics provides unprecedented possibilities for metrology. In this workshop we aim at exploring new opportunities and challenges arising from the presence of interactions and dissipation in quantum sensors. Many-body interactions lead to non-trivial many-body states and dynamics, which open a whole range of possibilities for metrology. On the one hand, it offers new resources for quantum-enhanced estimation, in particular the presence of quantum phase transitions and other many-body collective effects. On the other hand, it naturally motivates the study of metrology tasks that cannot be phrased as a phase estimation problem, such as the estimation of temperature or parameters characterizing non-equilibrium steady states, with tools developed in the context of quantum metrology. This sets the ground for establishing new
links between quantum metrology, many-body physics, open quantum systems, quantum optics, as well as thermodynamics.

This Workshop is hence a highly interdisciplinary event which will join experts from different communities to present their latest results, discuss open problems, as well as explore new interconnections. Relevant directions that will be covered include:

1. Quantum metrology in presence of environmental noise, including error correction techniques.
2. Quantum metrology with interacting systems, including quantum critical metrology.
3. Quantum estimation of environmental parameters, particularly quantum thermometry.

Early career researchers are highly encouraged to participate and present their results.
