Query: Experimental study of continuous variable quantum key distribution   It has been proven in the literature that the main technological factors
limiting the communication rates of quantum cryptography systems by single
photon are mainly related to the choice of the encoding method. In fact, the
efficiency of the used sources is very limited, at best of the order of a few
percent for the single photon sources and the photon counters can not be
operated beyond a certain speed and with a low order of detection efficiency.
In order to overcome partially these drawbacks, it is advantageous to use
continuous quantum states as an alternative to standard encodings based on
quantum qubits. In this context, we propose a new reconciliation method based
on Turbo codes. Our theoretical model assumptions are supported by experimental
results. Indeed, our method leads to a significant improvement of the protocol
security and a large decrease of the QBER. The gain is obtained with a
reasonable complexity increase. Also, the novelty of our work is that it tested
the reconciliation method on a real photonic system under VPItransmissionMaker.
