Quantum computing has long been dominated by proprietary machines locked behind corporate and national lab firewalls, but a different model is starting to take shape. A growing coalition of ...

A research group at the University of Geneva (UNIGE) demonstrates that the state of a quantum system can be inferred through ...

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.

Quantum systems tend to become less “quantum-y” as they interact with their environment. So when developing a mathematical description, it’s usually simpler just to view them as being closed off from ...
