Quantum Foundations

“Why do some things happen, and others don’t?”, “What determines the events we observe in Nature?” These have always been among the most recurrent and fascinating questions that scientists and philosophers have asked themselves. Trying to give a definitive answer remains a challenge today.

Quantum Mechanics is currently considered as the fundamental theory that describes the structure and the properties of matter at microscopic scales. This theory was developed to explain a long series of experiments whose results could not fit in the conceptual framework of classical theory. Many aspects of quantum mechanics are far from the classical notions of reality and causal relations. One of these is certainly the phenomenon known as Quantum Entanglement i.e. the possibility of having a system which is composed by more than a particle, but can only be seen as unique entity, regardless of the distance between their components.

This Research line is fully addressed within Quantum Information Lab and by exploring the fundamental underpinnings of quantum science we can tackles questions such as:
*What is quantum entanglement?
*Which is the gap between classical and quantum behavior?
*Can we improve our current technology through quantum effects?
