Title: Kyong Chun Lim: Innovator in Quantum Key Distribution
Introduction
Kyong Chun Lim is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of quantum key distribution, holding 2 patents that enhance the security and efficiency of cryptographic systems.
Latest Patents
One of his latest patents is a "Continuous variable quantum key distribution phase compensation system." This invention is utilized for continuous variable quantum key distribution (CVQKD) with asynchronous local oscillators. It involves a system for performing phase compensation using local oscillator (LO) phase estimation and feedback at a receiver (Bob), utilizing a pilot signal from a transmitter (Alice). The system also measures quantum state data using an LO with a predetermined phase at the receiver and estimates and feeds back the LO phase through multi-dimensional reconciliation (MDR).
Another notable patent is the "Method and apparatus for quantum key distribution on the basis of photon subtraction from the receiver." This invention relates to a method and apparatus for quantum key distribution according to a continuous-variable quantum key distribution protocol. It distributes the quantum key in a reverse post-processing manner and detects bit information from a received quantum state after photon subtraction at the receiver (Bob). This approach enhances security and increases the cryptographic key generation rate, as the cryptographic key remains protected from potential attackers.
