Unconditional security proof of long-distance continuous-variable quantum key distribution with discrete modulation. | LitMetric

Unconditional security proof of long-distance continuous-variable quantum key distribution with discrete modulation.

Phys Rev Lett

Institut Telecom/Telecom ParisTech, CNRS LTCI, 46, rue Barrault, 75634 Paris Cedex 13, France.

Published: May 2009

AI Article Synopsis

Article Abstract

We present a continuous-variable quantum key distribution protocol combining a discrete modulation and reverse reconciliation. This protocol is proven unconditionally secure and allows the distribution of secret keys over long distances, thanks to a reverse reconciliation scheme efficient at very low signal-to-noise ratio.
