This workshop is organized in the framework of the Foundational Questions Institute, FQXI, project: “Events” as we see them: experimental test of the collapse models as a solution of the measurement problem, and is sponsored by INFN.
The aim of the workshop is to discuss the possible limits of validity of quantum mechanics, the collapse models and, more generally, theories which go beyond the standard quantum mechanics, as well as experiments aiming to test them. Also, in this context, the role that gravity may play will be discussed.
From the theoretical point of view, since the Einstein-Bohr debate, quantum mechanics never stopped raising questions about its meaning. In particular, the transition from the microscopic world, where systems are observed in a superposition of different quantum states, to the macroscopic world, where systems have well defined positions (the so-called “measurement problem”), never stopped to puzzle the scientific community. For this reason, scientists are pushed to look for theories beyond the standard quantum formulation.
From the experimental point of view, quantum mechanics is the best verified available theory. It is therefore a very compelling challenge to look for possible small violations predicted by alternative quantum theories. The aim is either to put stronger observational bounds on the new theories, i.e. on model's parameters, or, much more exciting, to find a violation of standard quantum mechanics when compared with the new theories' predictions. In this framework, a deeper understanding of the possible limits of validity of the quantum superposition principle is an interesting experimental challenge.
