Variable Planck's constant and scaling properties of states on Weyl algebra
Piotr Ługiewicz, Lech Jakóbczyk, Andrzej Frydryszak
We consider the possible quantum effect for infinite systems produced by variations of the Planck's constant. Using the algebraic formulation of quantum theory we study behaviour o…
Two-qubit trace-norm geometric discord: the complete solution
Piotr Lugiewicz, Andrzej Frydryszak, Lech Jakobczyk
We present the complete solution of the problem of determination of trace-norm geometric discord for arbitrary two-qubit state. Final answer is achieved due to effective reduction…
From quantum to quantum via decoherence
Ph. Blanchard, P. Lugiewicz, R. Olkiewicz
Various physical effects resulting from decoherence are discussed in the algebraic framework. In particular, it is shown that the environment may induce not only classical properti…
