  • A class of Bell diagonal states and entanglement witnesses 
    Chruściński, Dariusz; Kossakowski, Andrzej; Młodawski, Krzysztof; Matsuoka, Takashi (2010)
    We analyze special class of bipartite states - so called Bell diagonal states. In particular we provide new examples of bound entangled Bell diagonal states and construct the class of entanglement witnesses diagonal in the ...
  • On classical and quantum liftings 
    Accardi, L.; Chruściński, Dariusz; Kossakowski, Andrzej; Matsuoka, Takashi; Ohya, Masanori (2011-02-01)
    We analyze the procedure of lifting in classical stochastic and quantum systems. It enables one to `lift' a state of a system into a state of `system+reservoir'. This procedure is important both in quantum information ...
  • On correlations and mutual entropy in quantum composed systems 
    Hirota, Yuji; Chruściński, Dariusz; Matsuoka, Takashi; Ohya, Masanori (2012-09-12)
    We study the correlations of classical and quantum systems from the information theoretical points of view. We analyze a simple measure of correlations based on entropy (such measure was already investigated as the degree ...
