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…
Quantum theory: kinematics, linearity and no-signaling condition
Mario Ziman, Peter Stelmachovic
We show that the linearity of an evolution of Quantum Mechanics follows from the definition of kinematics. The same result is obtained for an arbitrary theory with the state space…
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…
