unconditioned

• Quantum communication is a rising interdisciplinary field which combines classical communication and quantum mechanics . quantum key distribution protocol makes use of single photon of quanta - randomicity to achieve unconditioned security key distribution , especially which is the realism significance of research way in quantum information at present
  量子密码术是经典通信和量子物理相结合的一门新兴交叉科学。量子密钥分配( qkd )协议利用单光子固有的量子随机性实现具有无条件安全性的密钥分配，是目前量子信息领域中特别具有现实意义的研究方向。
