<div><br></div>
<blockquote>This talk reports the current status of the DARPA Quantum
Network, which became fully operational in BBN's Cambridge 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 the first QKD
system providing continuous operation across a metropolitan area. Four
more nodes have recently added to bring the total to 10 QKD nodes,
implemented with 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 current 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.</blockquote>
