Quanta, cats and socks: the nonlocal nature of reality

Can an object be in two places at the same time? Can a cat be alive AND dead at the same time? Is it possible for an observation made here and now to have an instantaneous effect on the other side of the universe? And what does this have to do with the socks of a CERN scientist?

Special guest lecture by Dr. Francesco Massel from  the Nanoscience Center, University of Jyväskylä.

About Francesco Massel

Francesco Massel got his Ph.D. in 2006 in Politecnico di Torino (Italy) working on ultracold gases, with the thesis "Hubbard-like Hamiltonian in optical lattices". After postdoc periods in Politecnico di Torino and Aalto University (Finland) working on ultracold fermionic gases, in 2010 he has started working on optomechanical systems.

Since 2014, he is leader of the "Open quantum systems dynamics" (formerly "Quantum optomechanics") group in the University of Jyväskylä. Their research focuses, on one hand, on the theoretical investigation of quantum systems in the presence of external driving fields, on the other we collaborate with experimentalists in the field of circuit quantum electrodynamics and nanomechanics.

Abstract of the lecture

Since the dawn of mankind, our senses have represented the way through which we build our picture of the natural world. In the quest for better explanations, modern science has lead us to devise and employ experimental apparatuses, from Galileo's telescope to particle accelerators, that allow us to probe nature in ever-increasing detail. These apparatuses have contributed to the discovery of phenomena that are qualitatively different from what we experience in our everyday life, thus revolutionizing our image of the world.

In his talk, he will focus on some intriguing aspects of quantum mechanics that seem to challenge the most our common perception of reality. Can an object be in two places at the same time? Can a cat be alive AND dead at the same time*? Is it possible for an observation made here and now to have an instantaneous effect on the other side of the universe? And what does this have to do with the socks of a CERN scientist*?

*no cats nor CERN scientists were harmed during the preparation of this talk.
