Mötesplats Rydberg - Quantum physics and the spirit of Copenhagen

Quantum physics and the spirit of Copenhagen

With Professor Klaus Mølmer, Niels Bohr Institute, Copenhagen University, Denmark.

This seminar is part of a series organised by Lund University in recognition of the International Year of Quantum Science and Technology (IYQ). All seminars in the series are presented on the Quantum in Lund website.

Abstract:
With his 1913 theory model of atoms and molecules, Niels Bohr joined Planck and Einstein as co-founder of the early quantum theory. In 1920, he was put in charge of the new institute in Copenhagen, that now carries his name, and he designed it as a modern, progressive, and international hub for a whole generation of young scientists from all over the world. Bohr’s own model of atoms turned out to be insufficient, while a new theory, quantum mechanics, was spearheaded by Heisenberg and Schrödinger in 1925-26.

Quantum mechanics provides a quantitative and precise description of all known microscopic phenomena from nuclear matter to molecules and solids. But the formulas of quantum mechanics deal with waves instead of particles, and they make strange and paradoxical predictions. Notably, Bohr and Einstein embarked on famous discussions about the interpretation of quantum mechanics. These discussions are still going on among the proponents of the Copenhagen interpretation, the  “Many-Worlds” interpretation, the  “pilot-wave” interpretation, and several others.

In the lecure, I will review the early development of quantum theory, Bohr’s and Einstein’s  argument in the discussions about its interpretation, and how elements in these discussions have triggered revolutionary ideas for new technologies.  Across personal preferences for one or another interpretation of the theory,  scientists and engineers today try to employ the weirdest features and paradoxes of quantum mechanics for practical applications in quantum computers, quantum communication networks and quantum precision sensors.
