A subcarrier multiplexing quantum key distribution is based on phase modulation polarization coding scheme. The key could be shared by several parallel sideband channels, and each sideband has a random and independent polarization which is synthesized by controlling the phase difference of subcarriers in two electro-optical phase modulators. The key rate could be increased multiply. The simulation result shows that the scheme works well.
