The DARPA Quantum Network

Note: This Lecture is in Lecture Theatre 1 at 2:00pm.

The world's first quantum cryptographic network is now operational beneath the streets of Cambridge, Mass., providing an extremely secure Virtual Private Network (VPN) between the campuses of Harvard University, Boston University, and BBN Technologies. Unlike conventional cryptography, our system bases its security assurances on the Heisenberg Uncertainty Principle, transmitting key material modulated onto single photons. This talk will introduce quantum cryptography (more properly Quantum Key Distribution) and describe the DARPA Quantum Network in some detail, with particular emphasis on its unusual networking aspects.

Mr. Elliott has led the design and successful implementation of a number of secure networks based on novel Internet technology for the United States, Canada, and the U.K. and has acted as senior advisor on a number of national and commercial networks including three LEO satellite constellations and Boeing's Connexion system. Mr. Elliott has particular expertise in wireless Internet technology, mobile "ad hoc" networks, quality of service issues, and novel routing techniques. At present he is leading the design and build-out of a very highly secure network protected by quantum cryptography. He holds over 125 patents pending or issued on network technology.
