[20040720] CV attack 2

Title Security bounds for continuous variables quantum key distribution
Authors: Miguel Navascues, Antonio Acin
Comments: See also F. Grosshans, quant-ph/0407148

Security bounds for key distribution protocols using coherent and squeezed states and homodyne measurements are presented. These bounds refer to (i) general attacks and (ii) collective attacks where Eve interacts individually with the sent states, but delays her measurement until the end of the reconciliation process. For the case of a lossy line and coherent states, it is first proven that a secure key distribution is possible up to 1.9 dB of losses. For the second scenario, the security bounds are the same as for the completely incoherent attack.

It looks important one. If one want to start a research about the CV quantum cryptography, this is the paper you should start seriously.

I start to study below one, but I think this article also useful.

First of all, I will try to introduce this article in our wiki page.. ^^

How would you like to know about a Water Sports resource, that displays all the Water Sports information on one website? Check out
Water Sports today. Not only do they have a good fitness book section, but they also have great articles on fitness. I was really impressed with the resources their webmster put together.
