DARPA量子网络的现状
Current status of the DARPA Quantum Network
摘要：
本文报道了DARPA量子网络的现状，该网络于2003年10月在BBN实验室全面运行，自2004年6月以来一直在哈佛大学，波士顿大学和BBN之间通过电信光纤运行的6个节点中连续运行。DARPA量子网络是世界上第一个量子密码网络，也可能是第一个在大都市地区提供连续操作的QKD系统。现在又增加了四个节点，使总数达到10个QKD节点。该网络支持各种QKD技术，包括通过光纤的相位调制激光器，通过光纤的纠缠和自由空间QKD。我们为这个网络提供了一个基本的介绍和理由，讨论了2005年2月网络中各种QKD硬件套件和软件系统的状态，并描述了我们迄今为止使用DARPA量子网络的操作经验。最后，我们讨论一下我们正在进行的工作。
英文摘要：
This paper reports the current status of the DARPA Quantum Network, which became fully operational in BBN's laboratory in October 2003, and has been continuously running in 6 nodes operating through telecommunications fiber between Harvard University, Boston University, and BBN since June 2004. The DARPA Quantum Network is the world's first quantum cryptography network, and perhaps also the first QKD systems providing continuous operation across a metropolitan area. Four more nodes are now being added to bring the total to 10 QKD nodes. This network supports a variety of QKD technologies, including phase-modulated lasers through fiber, entanglement through fiber, and freespace QKD. We provide a basic introduction and rational for this network, discuss the February 2005 status of the various QKD hardware suites and software systems in the network, and describe our operational experience with the DARPA Quantum Network to date. We conclude with a discussion of our ongoing work.
