Commuting operations factorise
Renato Renner, Ramona Wolf
Consider two agents, Alice and Bob, each of whom takes a quantum input, operates on a shared quantum system , and produces a quantum output. Alice and Bob's operations may commu…
The debate over QKD: A rebuttal to the NSA's objections
Renato Renner, Ramona Wolf
A recent publication by the NSA assessing the usability of quantum cryptography has generated significant attention, concluding that this technology is not recommended for use. Her…
Coherent attacks are stronger than collective attacks on DIQKD with random postselection
Martin Sandfuchs, Ramona Wolf
In a recent paper [Phys. Rev. Lett. 129, 050502 (2022)], the authors report on the implementation of a device-independent QKD protocol with random postselection, which was original…
Security of differential phase shift QKD from relativistic principles
Martin Sandfuchs, Marcus Haberland, V. Vilasini +1
The design of quantum protocols for secure key generation poses many challenges: On the one hand, they need to be practical concerning experimental realisations. On the other hand,…
