About optimal measurements in quantum hypothesizes testing
A. E. Allahverdyan, D. B. Saakian
We consider the problem of a state determination for a two-level quantum system which can be in one of two nonorthogonal mixed states. It is proved that for the two independent ide…
The broadcast quantum channel for classical information transmission
A. E. Allahverdyan, D. B. Saakian
It is well known that quantum theory forbids the exact copying of an unknown quantum state. Therefore in broadcasting of classical information by a quantum channel an additional co…
Multi-access channels in quantum information theory
A. E. Allahverdyan, D. B. Saakian
The multi-access channels in quantum information theory are considered. Classical messages from independent sources, which are represented as some quantum states, are transported b…
Data processing in quantum information theory
A. E. Allahverdyan, D. B. Saakian
The strengthened data processing inequality have been proved. The general theory have been illustrated on the simple example.
