摘要
Abstract
Quantum broadcast channels are the fundamental of quantum network communication.To use the channel efficiently and effectively,it is crucial to know the capacity region of the channel.In this paper, we focus on the capacity region problem of quantum broadcast channel with only one sender and two receivers.According to the quantum entanglement generation theorem, we present and prove the capacity theorems of noisy quantum broadcast channels, including classical-quantum and quantum-quantum capacity region theorems, by which we obtain the capacity region of the quantum broadcast channel with depolarizing noise.关键词
