去极化信道中的量子纠缠与经典通信

Quantum entanglement and classical communication through a depolarising channel

D. Bruss, L. Faoro, C. Macchiavello, M. Palma

摘要:

我们分析了纠缠在无记忆去极化信道中经典信息传输中的作用。利用该信道的各向同性性质,我们分析地证明了将经典比特编码成两个量子比特的纠缠态不能增加互信息。

英文摘要:

We analyse the role of entanglement for transmission of classical information through a memoryless depolarising channel. Using the isotropic character of this channel we prove analytically that the mutual information cannot be increased by encoding classical bits into entangled states of two qubits.
