Long-lived storage of a photonic qubit for worldwide teleportation

MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.

Probing Slow Relaxation and Many-Body Localization in Two-Dimensional Quasi-Periodic Systems

Most physical systems rapidly reach thermal equilibrium. Certain quantum-mechanical systems in the presence of strong applied disorder, however, can get stuck in nonequilibrium states forever. Such systems are said to be in the...

Prof. Ignacio Cirac receives Max-Planck Medal from the German Physical Society

The Max-Planck medal is the most prestigious award of the German Physical Society (DPG) for outstanding performances in the area of theoretical physics. It is given once a year to a brilliant scientist who is following in the...

The Rydberg constant and proton size from atomic hydrogen

At the core of the “proton radius puzzle” is a four–standard deviation discrepancy between the proton root-mean-square charge radii (rp) determined from the regular hydrogen (H) and the muonic hydrogen (µp) atoms. Using a...
