Latest work: Security of differential phase shift QKD from relativistic principles

with Martin Sandfuchs, Marcus Haberland, and V. Vilasini

20 years after its invention, we provide a full security proof of the differential phase shift protocol for quantum key distribution! The proof combines the entropy accumulation theorem with relativistic principles and techniques from quantum optics.

Latest publication: Quantum advantage in cryptography

with Renato Renner
Now published in the AIAA Journal!

We give an overview of the principles of quantum mechanics that enable information-theoretic security, why quantum cryptography is important, and discuss the state of the art of the field.
