Latest Patents

One of his latest patents is a quantum key distribution system. This system includes a sending terminal, a measurement terminal, a receiving terminal, and at least one polarization controller. The sending terminal generates a quantum optical signal and receives a detection result. The measurement terminal features a beam splitter and two single-photon detectors, which generate measurement optical signals based on the quantum optical signal. The receiving terminal is designed to receive the detection result. The polarization controller performs polarization processing on the quantum optical signal or the detection result using a target transmittance matrix, resulting in a polarized quantum optical signal or a polarized detection result.

Another notable patent is a photon phase modulating system. This invention utilizes a high-speed serial data transceiver to generate two high-speed electric pulse signals. After passing through a gain network, these signals drive an electro-optic phase modulator to achieve phase modulation of photon signals. This system allows for the realization of a four-phase modulation function needed by the BB84 quantum key distribution protocol without the need for a digital-to-analog converter or an analog switch. The dual-electrode electro-optic phase modulator scheme effectively reduces the requirements for the amplitude of the modulation driving signal, facilitating high-speed phase modulation that meets the demands of quantum key distribution.
