Title: Innovations of Joong-Seon Choe
Introduction
Joong-Seon Choe is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of quantum communication, holding a total of 18 patents. His work focuses on developing advanced technologies that enhance secure communication systems.
Latest Patents
One of his latest patents is a quantum key distribution system and operation method. This system utilizes a reference frame independent quantum key distribution protocol. It includes a quantum channel transmitter that generates a first quantum signal containing quantum information. This signal is provided to an external device through a quantum channel. Additionally, a first public channel transceiver generates an optical signal that includes first additional information related to the quantum key distribution operation. It transmits and receives this optical signal through a public channel. Furthermore, a second public channel transceiver receives the optical signal and generates a measurement result by measuring a circular polarization component of the optical signal. A quantum channel receiver then receives the first quantum signal, generates a second quantum signal by correcting polarization distortion, and demodulates the quantum information from the second quantum signal.
Another notable patent involves a beam tracking module, free-space quantum communication device, and free-space optical communication device. The beam tracking module is designed for free-space quantum communication. It includes a controller that determines the divergence angle of a reference beam based on divergence angle control data. The beam path control optical part outputs the reference beam, while the beam transmitter adjusts the divergence angle to ensure the reference beam is output with the determined divergence angle.
