From Einstein to Bell to Quantum Information

on 14-07-2023


In 1935, one of the most prominent pioneers of quantum mechanics co-authored an article aimed at persuading physicists to seek better (“more complete”) theories. 30 years later, a particle physicist trying his hand at philosophy on weekends was trying to take that view seriously. That endeavor engendered one of the most staggering results ever in physics: Bell’s theorem. Einstein's ambitious dream of supplanting quantum physics turned out to be more challenging than he thought. But on the flip side, another 30 years later began the era of quantum information. A direct continuation of Bell’s work in unveiling quantum advantages. In this talk, I will briefly introduce the concept of quantum entanglement, review the EPR argument and explain what Bell’s theorem states. Furthermore, I will explore the modern quantum information perspective on these questions, along with the applications and implications of the phenomenon known as Bell nonlocality.

This is an open talk by Flavien Hirsch, promoted by the QuLab of Instituto de Telecomunicações.

The talk will take place in person as well remotely at Instituto Superior Tecnico, Instituto de Telecomunicações, Torre Norte, Amphitheater EA3, on July 14, 2023.

Flavien Hirsch is currently a visiting researcher at the Quantum Photonics Laboratory at Instituto de Telecomunicações, interested mostly in quantum entanglement, Bell nonlocality, the applications of quantum information and philosophy of physics. After a master's degree in theoretical physics at the University of Geneva, he joined the group of Nicolas Brunner for a Ph.D. within the Group of Applied Physics, still in Geneva. He then stayed there for a short postdoc, before pursuing his academic research with Marcus Huber, at IQOQI Vienna, through a Swiss Postdoc Mobility grant. He eventually stayed in Vienna for 4 years overall, working in the group of Marcus Huber at IQOQI Vienna and the Technical University of Vienna. After more than 10 years in academic research (counting the master thesis), he could explore different facets of quantum mechanics, quantum information, entanglement, measurement incompatibility, Bell nonlocality and EPR steering, as well as some quantum thermodynamic, quantum key distribution and numerical tools for mathematics optimization.
