精确计算了有耗玻色子信道的经典容量。结果表明，它的Holevo信息不是超加性的，并且相干状态编码实现容量。作为一个例子，给出了远场，自由空间光通信的容量。
The classical capacity of the lossy bosonic channel is calculated exactly. It is shown that its Holevo information is not superadditive, and that a coherent-state encoding achieves capacity. The capacity of far-field, free-space optical communications is given as an example.
