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. What is the state of a quantum system?

Researchers around the world are racing to develop new quantum-based systems for sensing, communication, computing and control that have the promise of outperforming traditional systems. Creating ...

Building useful quantum technologies—from sensors to computers—requires generating highly complex entangled states, in which the properties of particles are deeply intertwined. Producing such states ...
