Cloning of orthogonal mixed states entails irreversibility
Michal Horodecki, Aditi Sen De, Ujjwal Sen
Orthogonal pure states can be cloned as well as deleted. However if there is an initial disorder in the system, that is for orthogonal mixed states, one cannot perform deletion. An…
Quantification of quantum correlation of ensemble of states
Michal Horodecki, Aditi Sen De, Ujjwal Sen
We present first measure of quantum correlation of an ensemble of multiparty states. It is based on the idea of minimal entropy production in a locally distinguishable basis measur…
No-deleting and no-cloning principles as consequences of conservation of quantum information
Michal Horodecki, Ryszard Horodecki, Aditi Sen De +1
We show that the no-deleting and no-cloning principles are implications of information conservation principle. This is unlike in classical physics, where cloning and deleting are p…
How to reuse a one-time pad and other notes on authentication, encryption and protection of quantum information
Jonathan Oppenheim, Michal Horodecki
Quantum information is a valuable resource which can be encrypted in order to protect it. We consider the size of the one-time pad that is needed to protect quantum information in…
Quantum information isomorphism: beyond the dillemma of Scylla of ontology and Charybdis of instrumentalism
Ryszard Horodecki, Michal Horodecki, Pawel Horodecki
In order to have the most safe way of dealing with unanalysable quantum whole the Copenhagen interpretation takes as a "frame of reference" the preparation parameters and outcomes…
Locally accessible information: How much can the parties gain by cooperating?
Piotr Badziag, Michal Horodecki, Aditi Sen De +1
We investigate measurements of bipartite ensembles restricted to local operations and classical communication and find a universal Holevo-like upper bound on the locally accessible…
