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…
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…
No-deleting and no-cloning principles as consequences of conservation of quantum information
Michal Horodecki, Ryszard Horodecki, Aditi Sen De +1
We show that the no-deleting and no-cloning principles are implications of information conservation principle. This is unlike in classical physics, where cloning and deleting are p…
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…
Separability of mixed quantum states: linear contractions approach
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki
Recently, a new and powerful separability criterion was introduced in [O. Rudolph, quant-ph/0202121] and [Chen {\it et al.}, quant-ph/0205017]. Composing the main idea behind the a…
Mixed-state entanglement and quantum communication
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki
We present basics of mixed-state entanglement theory. The first part of the article is devoted to mathematical characterizations of entangled states. In second part we discuss the…
