Limits for compression of quantum information carried by ensembles of mixed states
Michal Horodecki
We consider the problem of compression of the quantum information carried by ensemble of mixed states. We prove that for arbitrary coding schemes the least number of qubits needed…
Jaynes principle versus entanglement
Ryszard Horodecki, Michal Horodecki, Pawel Horodecki
We show, by explicit examples, that the Jaynes inference scheme based on maximization of entropy can produce inseparable states even if there exists a separable state compatible wi…
Reduction criterion of separability and limits for a class of protocols of entanglement distillation
Michal Horodecki, Pawel Horodecki
We analyse the problem of distillation of entanglement of mixed states in higher dimensional compound systems. Employing the positive maps method [M. Horodecki et al., Phys. Lett.…
Are there basic laws of quantum information processing?
Michal Horodecki, Ryszard Horodecki
We prove within the standard quantum formalism without reduction postulate that the no-cloning theorem and the principle of no-increasing of entanglement under local actions and on…
