INRIM Quantum Physics Research Group recently published in the scientific magazine Nature Physics

INRIM Quantum Physics research group, in collaboration with researchers from Politecnico di Milano, Tel Aviv University, and University of Bristol, just implemented a novel measurement protocol.

This method, called "protective measurement", allows to obtain the average value of a physical observable by measuring a single particle instead of a particle ensemble. 

The paper describing the experiment, entitled "Determining the quantum expectation value by measuring a single photon", was published in Nature Physics.
