A de Finetti representation for finite symmetric quantum states
Robert Koenig, Renato Renner
Consider a symmetric quantum state on an n-fold product space, that is, the state is invariant under permutations of the n subsystems. We show that, conditioned on the outcomes of…
Lower and upper bounds on the secret key rate for QKD protocols using one--way classical communication
B. Kraus, N. Gisin, R. Renner
We investigate a general class of quantum key distribution (QKD) protocols using one-way classical communication. We show that full security can be proven by considering only colle…
Universally composable privacy amplification against quantum adversaries
Renato Renner, Robert Koenig
Privacy amplification is the art of shrinking a partially secret string Z to a highly secret key S. We show that, even if an adversary holds quantum information about the initial s…
A Generic Security Proof for Quantum Key Distribution
Matthias Christandl, Renato Renner, Artur Ekert
Quantum key distribution allows two parties, traditionally known as Alice and Bob, to establish a secure random cryptographic key if, firstly, they have access to a quantum communi…
