<p>Abstract: A method and system for quantum key distribution (QKD) between a first location and a second location through an intermediate location. The system and method include executing a quantum phase between each of the first and second locations and the intermediate location to determine a first location raw data string at the first location, a first-intermediate raw data string at the intermediate location, a second location raw data string at the second location, and a second-intermediate raw data string at the intermediate location, respectively; calculating, at the intermediate location, announcement data based on a function of the first and second-intermediate raw data strings; announcing, at the intermediary location, the announcement data over a classical channel; and deriving, at each of the first and second locations, a secret key based on the available data and on communications between the first and second locations via a classical channel.</p> |
