Fully Device Independent Quantum Key Distribution
We rigorously provide the device-independent security of an entanglement-based protocol building on Ekert's original proposal for quantum key distribution.

Face2Face: Real-Time Face Capture and Reenactment of RGB Videos
Face2Face is an approach for real-time facial reenactment of a monocular target video sequence (e.g., Youtube video). Our goal is to animate the facial expressions...
