In collaboration with Andreas Wallraff and his team, our group has built "dice" that produce certifiably perfect random numbers. The experiment uses entagled superconducting qubits and a Bell test to amplify imperfect randomness into randomness that is certified by quantum physics.

Our group leader, Prof. Renner, had a great conversation with Curt Jaimungal on Theories of Everything about the Frauchiger-Renner paradox, quantum foundations, and what happens when quantum mechanics is applied to its own observers. Full conversation here: https://youtu.be/6PJ8NI3v5Ss
Our group is organizing a summer school to take place in August 2026.
This five-day event will cover theoretical and experimental aspects of quantum cryptography, aiming to provide high-level training to young researchers entering this field.
See https://indico.global/event/9672/ for more details! The application deadline is April 15.
