Using Cascade in Quantum Key Distribution

This is a public version of the code used in Using Cascade in Quantum Key Distribution [arxiv]. This was built for v2.0.2 of the Open QKD Security package.

The code computes key rates and plots the figures from the paper. To plot Fig 1 and 2, run Cascade/qubitBB84/main.m. To plot Fig 3 and 4, run Cascade/DecoyBB84/main.m. For Fig 1 and Fig 2, set replaceProb=0 and replaceProb=0.2 respectively, for Fig 2 and 4 set perturbProb=0.0 and perturbProb=0.2 respectively..
