- Abstract: This paper investigates a reconciliation method in order to establish an
errorless secret key in a QKD protocol. Classical key distribution protocols
are no longer unconditionally secure because computational complexity of
mathematical problems forced hardships. In this context, QKD protocols offer a
highest level of security because they are based on the quantum laws of
physics. But, the protocol performances can be lowered by multiples errors. It
appears clearly that reconciliation should be performed in such a situation in
order to remove the errors as for the legitimate partners. The proposed method
accomplishes reconciliation by using QTC in the special problem of
sideinformation source coding (Slepian-Wolf coding model). Our theoretical
hypothesis are sustained by experimental results that confirm the advantage of
our method in resolving reconciliation problem compared to a recent related
work. Indeed, the integration of our method generates an important progess in
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.
