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…
