    • Operating beneath streets of Cambridge, Mass
    • DARPA Quantum Network links BBN?s campus to Harvard University
    • BBN is developing a practical network with inband encryption and out-of-band key distribution
    • Uses quantum mechanics to perform data encryption
    • Quantum cryptography was invented by Charles Bennet and Giles Brassard in 1980s
      • Quantum Key Distribution uses single photon of light
      • Single Quantum Key Distribution Network limited to 50 km
      • Would require a QKD Network of trusted nodes
    • BBN was a developer of the ARPANET, made the first router
    • QKD is research is being conducted at NIST (Part of Department of Commerce
