Quantum key distribution prototype
This thesis covers the basics of cryptography, both classical and the newer quantum-based
approches. Further, it details an implementation of a BB84-based quantum key distribution
system currently under construction, focusing on the controlling hardware and FPGA-based
software. The overarching goal is to create a system impervious to currently known attacks
on such systems.
The system is currently running at 100 Mbit/s, though the goal is to double this as
the design nears its completion. The system currently chooses encoding base, bit value and
whether a state is a socalled decoy state. However, the modulator for bit encoding is not
yet operational. Output for decoy state generation, however, is fully functional.
Finally, the thesis describes what steps are necessary to reach a complete BB84-based
quantum key distribution system implementing decoy states.
