Abstract
A team from BBN Technologies, Boston University, and Harvard University has recently built and begun to operate the world's first Quantum Key Distribution (QKD)network under DARPA sponsorship. The DARPA Quantum Network became fully operational on October 23, 2003 in BBN's laboratories, and in June 2004 was fielded through dark fiber under the streets of Cambridge, Mass., to link our campuses with non-stop quantum cryptography, twenty-four hours per day. As of December 2004, it consists of six nodes. Four are 5 MHz, BBN-built BB84 systems designed for telecommunications fiber and inter-connected by a photonic switch. Two are the electronics subsystems for a high speed free-space system designed and built by NIST. This paper describes the motivation for our work, the current status of the DARPA Quantum Network, its unique optical switching and key relay protocols, and our future plans.
