Title: Guilu Long: Innovator in Quantum Communication
Introduction
Guilu Long is a prominent inventor based in Beijing, China. He has made significant contributions to the field of quantum communication, holding 2 patents that showcase his innovative approach to secure communication methods.
Latest Patents
One of his latest patents is titled "Quantum secure direct communication method and apparatus based on one-way transmission." This invention relates to a method and apparatus that utilizes one-way transmission to ensure secure communication. The transmitting terminal performs error-correction anti-loss encoding on the message to be transmitted, obtaining a code word that is then encrypted using a negotiated encryption key. The resulting ciphertext message is encoded onto a quantum state and transmitted through a quantum channel to the receiving terminal.
Another notable patent is the "Secure relay-based quantum communication method and communication network." This method involves a transmitter encrypting plaintext information to create ciphertext, which is then sent to a repeater node using a quantum communication protocol. The ciphertext is transmitted step by step through at least one repeater node, allowing for long-distance communication while minimizing the risk of eavesdropping.
