Quantum inference of states and processes
Miroslav Jezek, Jaromir Fiurasek, Zdenek Hradil
The maximum-likelihood principle unifies inference of quantum states and processes from experimental noisy data. Particularly, a generic quantum process may be estimated simultaneo…
Optimal discrimination of mixed quantum states involving inconclusive results
Jaromir Fiurasek, Miroslav Jezek
We propose a generalized discrimination scheme for mixed quantum states. In the present scenario we allow for certain fixed fraction of inconclusive results and we maximize the suc…
Discrimination between non perfectly known states
Miroslav Jezek
Discrimination task is treated in the case of only partial prior information from measurements of unknown states. The construction of the optimal discrimination device and estimati…
Finding optimal strategies for minimum-error quantum-state discrimination
M. Jezek, J. Rehacek, J. Fiurasek
We propose a numerical algorithm for finding optimal measurements for quantum-state discrimination. The theory of the semidefinite programming provides a simple check of the optima…
