真实多方量子纠缠抑制多端口经典信息传输
Genuine Multiparty Quantum Entanglement Suppresses Multiport Classical Information Transmission
摘要:
我们建立了一个多体量子态作为多端口量子信道的经典信息传输能力与量子态的真实多体纠缠之间的普适互补关系。经典的信息传输是通过量子密集编码协议从一个发送者到多个接收者,发送者和接收者共享多方量子态。这个关系适用于任意维度中任意数目的任意纯态或任意混合量子态。
英文摘要:
We establish a universal complementarity relation between the capacity of classical information transmission by employing a multiparty quantum state as a multiport quantum channel, and the genuine multipartite entanglement of the quantum state. The classical information transfer is from a sender to several receivers by using the quantum dense coding protocol with the multiparty quantum state shared between the sender and the receivers. The relation holds for arbitrary pure or mixed quantum states of an arbitrary number of parties in arbitrary dimensions.
