• Generation of symbols according to a given constellation of points with an associated distribution;
• Digital Signal Processing of those symbols to generate a sequence to apply on a modulator;
• Interface to apply the sequence to the hardware;
• Estimation of Alice's parameters (in particular the average number of photons per symbols);
• Alice's server code.

Command line usage

A command line is shipped with the project to be able to launch Alice's server. The first step is to create a configuration file. This can be done with a command line tool shipped with the qosst-core package (which is a dependency of qosst-alice):

qosst configuration create

This will create the default configuration file at the location config.toml (you change the location with the -f or --file option). For more information on the meaning of each parameter in the configuration and how to change them, check the qosst tutorial.

Alice's server can then be launched with the following command:

qosst-alice -f config.toml

License

As for all submodules of QOSST, qosst-alice is shipped under the Gnu General Public License v3.
