**Quantum Metrology**

**Quantum metrology**aims at exploiting quantum mechanics to perform measurements whose precision is not achievable by means of purely classical approaches.

Among the next-generation of quantum technologies, that are expected to affect the paradigm for information and communication technology in a radical way, quantum metrology is definitely one of the most promising.

In my research I focus on the derivation of the ultimate limits on the measurement precision posed by quantum mechanics, with a particular attention to the multi-parameter case and in the presence of noise and decoherence.

**Quantum Control **

As it happens in “classical technologies”, where the effect of noise is neutralized by monitoring and controlling the signal and its environment,

In my research I focus on control strategies based on time-continuous monitoring and feedback, with applications to quantum state engineering and quantum metrology. A major attention is devoted to

**quantum control**is going to play a fundamental role for the development of noise-resilient protocols based on quantum mechanics.In my research I focus on control strategies based on time-continuous monitoring and feedback, with applications to quantum state engineering and quantum metrology.

**quantum opto-mechanical systems**, such as oscillating mirrors or levitating nanosphere interacting with quantum light.**Characterization of Continuous-Variable Quantum Systems**

**Continuous-variable quantum systems**are described by position and momentum operators obeying the canonical commuation relation. They are ubiquitous in quantum physics as this formalism is able to describe quantum light, trapped ions, mechanical oscillators and atomic ensembles.

**Gaussian systems**represent a specific subclass of continuous-variable quantum systems that, at the same time, can be efficiently described mathematically and exploited for quantum technology purposes.

A part from studying Gaussian systems and their applications in quantum technologies, in my research I focus on the characterization of

**non-Gaussian states**and operations, deriving measures and criteria able to describe this class of states whose usefulness in quantum technologies has been demonstrated in the literature.
