Secure key from bound entanglement
Karol Horodecki, Michal Horodecki, Pawel Horodecki +1
We characterize the set of shared quantum states which contain a cryptographically private key. This allows us to recast the theory of privacy as a paradigm closely related to that…
Quantum information isomorphism: beyond the dillemma of Scylla of ontology and Charybdis of instrumentalism
Ryszard Horodecki, Michal Horodecki, Pawel Horodecki
In order to have the most safe way of dealing with unanalysable quantum whole the Copenhagen interpretation takes as a "frame of reference" the preparation parameters and outcomes…
Direct estimation of functionals of density operators by local operations and classical communication
Carolina Moura Alves, Pawel Horodecki, Daniel K. L. Oi +2
We present a method of determining important properties of a shared bipartite quantum state, within the ``distant labs'' paradigm, using \emph{only} local operations and classical…
Compressing compound states
Michal Horodecki, Pawel Horodecki, Jonathan Oppenheim
Quantum compression can be thought of not only as compression of a signal, but also as a form of cooling. In this view, one is interested not in the signal, but in obtaining purity…
Optimal strategy for a single-qubit gate and trade-off between opposite types of decoherence
Robert Alicki, Michal Horodecki, Pawel Horodecki +3
We study reliable quantum information processing (QIP) under two different types of environment. First type is Markovian exponential decay, and the appropriate elementary strategy…
