A hybrid encoding design based on differential phase shift system
The differential shift phase system features a high rate of generating keys, high speed of coding, powerful ability of being not disturbed and having a long transmission distance and so on. On the analysis of Pockels effect, a hybrid encoding design was proposed which is based on the differential shift phase system. In this design, the transmitting uses the Pockels effect to have the polarization, phase and time encoded. The receiving terminal decodes by the inference of phase and the control of measuring time. Compared with traditional differential shift phase system analysis, it increases the relativity of differential shift phase code and raises a higher rate of generating quantum keys.
