Quantum Chaos and Quantum Information: Interactions and Implications
Arul Lakshminarayan, Karol Życzkowski
The notion of Shannon entropy is crucial for the theory of classical information. In quantum information theory, an analogous key role is played by the von Neumann entropy: quantum…

Spectral delineation of Markov Generators: Classical vs Quantum
Dariusz Chruściński, Sergey Denisov, Wojciech Tarnowski +1
The celebrated theorem of Perron and Frobenius implies that spectra of classical Markov operators, represented by stochastic matrices, are restricted to the unit disk. This propert…

Channel nonlocality under decoherence
Albert Rico, Moisés Bermejo Morán, Fereshte Shahbeigi +1
The implementation of realistic quantum devices requires a solid understanding of the nonlocal resources present in quantum channels, and the effects of decoherence on them. Here w…
