From Bell’s theorem to the device-independent quantum information scenario

Bell’s theorem proved the existence of quantum correlations with no classical analogue. After reviewing this fundamental result, we show how Bell non-local correlations are the crucial ingredient for device-independent quantum information applications. In this paradigm, devices are seen as uncharacterised quantum black boxes processing classical information and protocols are built without requiring any device modelling. This device-independent property guarantees that the protocol performance is self-certified and, in particular, provides the strongest form of quantum security.

NEW LOCATION STARTING 2025

The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the Gorlaeus building, lecture hall CM 1.26 (first floor, near main entrance on Einsteinweg 55). Before the Colloquium, there is a common dinner in the Beta Café (far end of the first floor, see map). This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium.

We count on your presence if you register, please do show up. Meal registrations may close earlier, when 80 persons have signed up.
