The operational meaning of min- and max-entropy
Robert Koenig, Renato Renner, Christian Schaffner
We show that the conditional min-entropy Hmin(A|B) of a bipartite state rho_AB is directly related to the maximum achievable overlap with a maximally entangled state if only local…
Robust Cryptography in the Noisy-Quantum-Storage Model
Christian Schaffner, Barbara Terhal, Stephanie Wehner
It was shown in [WST08] that cryptographic primitives can be implemented based on the assumption that quantum storage of qubits is noisy. In this work we analyze a protocol for the…
Composing Quantum Protocols in a Classical Environment
Serge Fehr, Christian Schaffner
We propose a general security definition for cryptographic quantum protocols that implement classical non-reactive two-party tasks. The definition is expressed in terms of simple q…
