Reconciliation protocol is used in quantum key distribution to reverse the error bits. Cascade is the most famous reconciliation protocol. It uses BINARY to correct errors and traces back into history records to find another error. In this paper, we implement the Cascade protocol and carry out some experiments for different BER, where BER is bit error rate for qubits. From the result of experiments, we found the efficiency of Cascade is approximate to the theoretical limitation.
