Common origin of no-cloning and no-deleting principles - Conservation of information
Michal Horodecki, Ryszard Horodecki, Aditi Sen De +1
We discuss the role of the notion of information in the description of physical reality. We consider theories for which dynamics is linear with respect to stochastic mixing. We poi…

Unitarity as preservation of entropy and entanglement in quantum systems
Florian Hulpke, Uffe V. Poulsen, Anna Sanpera +3
The logical structure of Quantum Mechanics (QM) and its relation to other fundamental principles of Nature has been for decades a subject of intensive research. In particular, the…

Local indistinguishability: more nonlocality with less entanglement
Michal Horodecki, Aditi Sen De, Ujjwal Sen +1
We provide a first operational method for checking indistinguishability of orthogonal states by local operations and classical communication (LOCC). This method originates from the…
