A new way to decipher quantum systems
Université de GenèvePeer-Reviewed Publication
What is the state of a quantum system? Answering this question is essential for exploiting quantum properties and developing new technologies. In practice, this characterisation generally relies on direct measurements, which require extremely well-controlled systems, as their sensitivity to external disturbances can distort the results. This constraint limits their applicability to specific experimental contexts. A team from the University of Geneva (UNIGE) presents an alternative approach, tailored to open quantum systems, in which the interaction with the environment is turned into an advantage rather than an obstacle. Published in Physical Review Letters – with the ‘Editor's Suggestion’ label – this work brings quantum technologies a step closer to real-world conditions.
