Description of quantum dynamics of open systems based on collision-like models
Mario Ziman, Peter Stelmachovic, Vladimir Buzek
Master equations in the Lindblad form describe evolution of open quantum systems that is completely positive and simultaneously has a semigroup property. We analyze a possibility t…
Quantum Information approach to the Ising model
P. Štelmachovič, V. Bužek
We present detailed analytical calculations for an 1D Ising ring of arbitrary number of spin-1/2 particles, in order to reveal entanglement properties of the stationary states. We…
Role of entanglement and correlations in dense coding
Mario Ziman, Vladimir Buzek
Usually it is assumed that quantum dense coding is due to quantum entanglement between two parties. We show that this phenomenon has its origin in {\em correlations} between two pa…
Simulation of Markovian quantum dynamics on quantum logic networks
Matyas Koniorczyk, Vladimir Buzek, Peter Adam +1
We study how generators of Markovian dynamics of a qubit can be simulated using a programmable quantum processor.
Quantum homogenization
M. Ziman, P. Stelmachovic, V. Buzek +3
We design a universal quantum homogenizer, which is a quantum machine that takes as an input a system qubit initially in the state and a set of N reservoir qubits initially pre…
Recycling of quantum information: Multiple observations of quantum clocks
Vladimir Buzek, Peter L. Knight, Nobuyuki Imoto
How much information about the original state preparation can be extracted from a quantum system which already has been measured? That is, how many independent (non-communicating)…
