Local control of remote entanglement
Peter Stelmachovic, Marian Rosko
We address the problem of the generation of entanglement. We focus on the control of entanglement shared by two non-interacting parties and via interaction with a third par…

Instability and entanglement of the ground state of the Dicke model
Vladimir Buzek, Miguel Orszag, Marian Rosko
Using tools of quantum information theory we show that the ground state of the Dicke model exhibits an infinite sequence of instabilities (quantum-phase-like transitions). These tr…

Generalized measurements via programmable quantum processor
Marian Rosko, Vladimir Buzek, Paul Robert Chouha +1
We show that it is possible to control the trade-off between information gain and disturbance in generalized measurements of qudits by utilizing the programmable quantum processor.…
