講　題：Building quantum channels

摘　要：

In quantum information theory, people ask whether there exists a quantum channel sending a particular input state to a particular output state.

Here, states are represented as positive operators with trace one. In this talk, we will show some properties of quantum channels and answer this question.

Moreover, we will show that the existence of a quantum channel between two compact normal operators is ensured by an inclusion relation of their numerical ranges.
