AIT QKD R10 Software

This is the AIT QKD Software Suite containing Q3P, the Q3P KeyStore, QKD Modules, Cascade, and others.

For scientists, universities, and security centered companies who want to concentrate on certain topics of QKD like sifting or error correction or simply use the off-the-shelf toolchain for their products the AIT QKD R10 is a full featured quantum key distribution implementation. Besides been a free open source solution the AIT comes with well defined interfaces and well documented sources which already have been used by several teams around the globe.

This is the public, free repository. We do have additional stuff like LDPC error correction, QKD presfiting and QKD GUI but we currently do not ship them for free of charge. If you have interest in these please contact us.
Change per October 10th, 2017: due to export restrictions by Europen law ( we are no longer able to provide this AIT QKD Software as a public free Open Source solution.

The source code is arranged as a CMake (see: project in a git (see: repository. The reference machines is Debian Debian 8 ("Jessie"). Any other Linux distribution might work as well, e.g. Ubuntu, RedHat, SuSE, Gentoo or Mint, but this is not tested yet.
