Quantum Communication
- Quantum key distribution
- Our group is developing a 1xN plug and play QKD (Quantum Key Distribution) system and applying it to a field test bed for moving forward to commercialization. In addition, we are conducting research on the latest QKD implementation technologies such as MDI (Measurement Device Independent) and TF (Twin-field). Moreover, we are focusing on the development of QKD chip implemented with LiNbO3 material.
- Quantum authentication and signature
- We are researching quantum authentication and quantum signature technologies necessary for secure communication between quantum nodes in the future quantum internet era.
- Quantum internet
- In preparation for the upcoming quantum internet era, we are researching long distance quantum communication technology that connects quantum computing and quantum sensing nodes.
