Quantum Cryptography in Practice

by Chip Elliott (Principal Engineer, DARPA Quantum Network Project, 
BBN Technologies, Cambridge, MA)

ABSTRACT

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.
