A Tight High-Order Entropic Quantum Uncertainty Relation With Applications
Ivan B. Damgaard, Serge Fehr, Renato Renner +2
We derive a new entropic quantum uncertainty relation involving min-entropy. The relation is tight and can be applied in various quantum-cryptographic settings. Protocols for quant…
On the impossibility of extracting classical randomness using a quantum computer
Yevgeniy Dodis, Renato Renner
In this work we initiate the question of whether quantum devices can provide us with an almost perfect source of classical randomness, and more generally, suffice for classical cry…
Unifying classical and quantum key distillation
Matthias Christandl, Artur Ekert, Michal Horodecki +3
Assume that two distant parties, Alice and Bob, as well as an adversary, Eve, have access to (quantum) systems prepared jointly according to a tripartite state. In addition, Alice…
One-and-a-half quantum de Finetti theorems
Matthias Christandl, Robert Koenig, Graeme Mitchison +1
We prove a new kind of quantum de Finetti theorem for representations of the unitary group U(d). Consider a pure state that lies in the irreducible representation U_{mu+nu} for You…
Security of Quantum Key Distribution
Renato Renner
We propose various new techniques in quantum information theory, including a de Finetti style representation theorem for finite symmetric quantum states. As an application, we give…
