Purification and correlated measurements of bipartite mixed states
Jan Bouda, Vladimir Buzek
We prove that all purifications of a non-factorable state (i.e., the state which cannot be expressed in a form ) are entangled. We also show that for any bipa…
To the nonlinear quantum mechanics
Miroslav Pardy
The Schroedinger equation with the nonlinear term is derived by the natural generalization of the hydrodynamical model of quantum mechanics. The nonlinear term appears to be logica…
Thermalizing Quantum Machines: Dissipation and Entanglement
Valerio Scarani, Mario Ziman, Peter Stelmachovic +2
We study the relaxation of a quantum system towards the thermal equilibrium using tools developed within the context of quantum information theory. We consider a model in which the…
Dynamics of open quantum systems initially entangled with environment: Beyond the Kraus representation
Peter Stelmachovic, Vladimir Buzek
We present a general analysis of the role of initial correlations between the open system and an environment on quantum dynamics of the open system.
Wigner-function description of quantum teleportation in arbitrary dimensions and continuous limit
M. Koniorczyk, V. Buzek, J. Janszky
We present a unified approach to quantum teleportation in arbitrary dimensions based on the Wigner-function formalism. This approach provides us with a clear picture of all manipul…
On the local unitary equivalence of states of multi-partite systems
Mario Ziman, Peter Stelmachovic, Vladimir Buzek
Two pure states of a multi-partite system are alway are related by a unitary transformation acting on the Hilbert space of the whole system. This transformation involves multi-part…
