    "abstract": "We present the application of quantum key distribution technologies to\nfiber-based broadband passive optical access networks. This application is\nbased on our 850 nm wavelength gigahertz clock-rate single-receiver system, is\ncompatible with existing telecommunications fiber and exploits a wavelength\nband not currently utilized in access networks. The developed quantum key\ndistribution networks are capable of transmitting over distances consistent\nwith the span of access links for metropolitan networks (10 km), at clock\nfrequencies ranging up to 3 GHz.",
