Integrated Quantum Control Protocol

Classical cryptography protocols are becoming vulnerable due to increasing computer power. However, optical fibers provide another method of securing the communication, by means of quantum cryptography. The concept of encoding the information in polarization states of photons has proven to be unconditionally secure. A few protocols have been proposed but the practical implementation of most of them have posed complications.

In this thesis work, a Quantum control protocol is proposed to safeguard a secure transaction over an optical network. The protocol provides a robust re-configurable architecture capable of incorporating several promising quantum cryptography protocols. The quantum control protocol has been prototyped on a FPGA test bed. The prototype yielded an error free transaction across the network. Thus, validating the claim of a practically realizable secure system.
