I have been making the switch away from Matlab to Python recently. The excellent quantum toolbox in Python (QuTiP) has been one of the many bright spots, enabling relatively complex problems to be easily simulated. Catherine Holloway, a fellow IQCer1, recently switched to QuTiP as well. The QuTiP blog recently posted an article about Catherine's use of the toolbox to simulate a quantum key distribution system. Here is a link to her exceptionally well documented code: [HTML] [Python Source]
