Fiber-based metropolitan quantum communication

Principal investigator
Introduction

The optical fiber based quantum communication laboratory has long practiced interdisciplinary and integration between research fields. Guided by national major strategic needs and frontier interdisciplinary, it has gradually become a laboratory that utilizes photons as information carriers and optical fibers as transmission medium, and focuses experimentally on crucial scientific and technical challenges in general quantum information physics and conducts relevant scientific research, which involves exploring quantum cryptography and quantum communications, and developing quantum information technologies.
The main research areas include: technical studies in long distance measurement device independent quantum key distribution, and based on new metropolitan quantum communication networks of measurement device independent quantum key distribution, investigating and expanding its network abilities, security analysis, and practical effects; aiming at challenges of fiber resource shortage and high costs in practical applications, and by researching new multiplexing techniques and ways to reduce Raman noise, experimentally verify the possibility of the quantum information technologies integrating with classical communication in various environments, and exploring the metropolitan wavelength division multiplexed network; based on practical conditions, improving the security of ground network devices, and combining cold atom quantum repeaters, extending the secure distance of quantum communications and developing a complete quantum network; creating a high brightness quantum entanglement source in the fiber and find its application on the quantum teleportation over metropolitan network; experimental demonstrating new Quantum Key distribution protocols such as quantum bit commitment, quantum data locking.
