Two Experts talking Quantum

Ignacio Cirac is one of the five directors at the Max Planck Institute of Quantum Optics and head of the theory division, for which Flore Kunst works as a postdoc. As a Max-Planck-Harvard Postdoctoral Fellow, she develops new theories about non-equilibrium topological phases within the single-particle limit and in many-body systems. During this talk, they explore some basics of Quantum Physics, Quantum Computers, and in the end, the relevance of a proposal from 1995 by Ignacio Cirac and Peter Zoller published in the Physical Review Letter called “Quantum Computations with Cold Trapped Ions”. This was the first working concept for a Quantum Computer. In Nature Reviews Physics from May 18th., 2020, Iulia Georgescu describes it as followed: "(...) when it comes to the first conception of how to actually build a quantum computer, one result stands out. On 15 May 1995, a paper by Ignacio Cirac and Peter Zoller was published in Physical Reviews Letters. It showed that atomic ions, trapped in a vacuum and cooled using lasers, could be used as qubits with which elementary quantum logic operations could be performed. The Cirac–Zoller paper turned quantum computing from a bold theoretical idea into an experimental race to build an actual device." (https://www.nature.com/articles/s42254-020-0189-1)
