A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment.

Network tomography is an indirect, measurement-based approach for inferring the internal characteristics of complex networks, such as traffic load, congestion points and failure localisation, ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...
