  • Passivity, complete passivity, and virtual temperatures 

    Skrzypczyk, Paul; Silva, Ralph; Brunner, Nicolas (OSA, 2015-05-19)
    Article
    Open Access
    We give a simple and intuitive proof that the only states which are completely passive, i.e., those states from which work cannot be extracted even with infinitely many copies, are Gibbs states at positive temperatures. ...
  • Thermodynamic cost of creating correlations 

    Huber, Marcus; Perarnau-Llobet, Martí; Hovhannisyan, Karen V.; Skrzypczyk, Paul; Klöckl, Claude; Brunner, Nicolas; Acín, Antonio (IOP, 2015-06-10)
    Article
    Open Access
    We investigate the fundamental limitations imposed by thermodynamics for creating correlations. Considering a collection of initially uncorrelated thermal quantum systems, we ask how much classical and quantum correlations ...
