A conversation that explores how quantum physics, born as a revolutionary theory a century ago, has become the basis of the new technological revolution. The ability to understand and manipulate matter at the atomic scale is giving rise to extraordinary applications: computers capable of solving previously impossible problems, sensors of unsuspected precision or practically inviolable communications. Physicist Ignacio Cirac, a world pioneer in quantum computing, and popularizer and writer Sònia Fernández Vidal will discuss the current state of quantum technologies and their potential to transform the future of science and society.
