| Outline of Final Research Achievements |
Developing the previous project: ``quantum fading channel and its information carrying limit, coding-decoding, and modulation," we have considered an application to wireless quantum communications. First, we applied the theory of a quantum fading channel to multi-mode quantum systems and considered the multiple noise case. Considering multi-mode quantum systems is essential to treat ``entanglement." We also applied the model to some application protocols of entanglement and clarify various properties. Moreover, we extended the formula of a channel matrix to asymmetric signals.
