Towards efficient algorithm deciding separability of distributed quantum states
Piotr Badziag, Pawel Horodecki, Ryszard Horodecki
It is pointed out that separability problem for arbitrary multi-partite states can be fully solved by a finite size, elementary recursive algorithm. In the worse case scenario, the…
Generalised Smolin states and their properties
Remigiusz Augusiak, Pawel Horodecki
Four qubit bound entangled Smolin states are generalised in a natural way to even number of qubits. They are shown to maximally violate simple correlation Bell inequalities and, as…
Thermodynamics of quantum informational systems - Hamiltonian description
Robert Alicki, Michal Horodecki, Pawel Horodecki +1
It is often claimed, that from a quantum system of d levels, and entropy S and heat bath of temperature T one can draw kT(ln d -S) amount of work. However, the usual arguments base…
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…
