Descrizione generata automaticamente

Quantum sensing represents one of the pillars of current quantum technologies. In particular, optical phase sensing has proven to be of interest in several applications ranging from gravitational waves detection to sensing of biological specimens. In such practical scenarios, quantum-enhanced measurement sensitivities can be demonstrated exploiting squeezed states of light. The aim of this research line is to demonstrate a sub-shot-noise precision when measuring the optical phase shift among the two arms of an interferometer exploiting single-mode squeezed states.
