Overview of Academic Research
My research interest is on experiments in quantum communication, focusing on overcoming core challenges in high-security protocols such as: Measurement-Device-Independent Quantum Key Distribution (MDI-QKD, TF-QKD), Device-Independent Quantum Random Number Generation (DI-QRNG). The key achievements includes:
The first complete experimental demonstration of MDI-QKD, which eliminating all detector-side attacks (“highlights of the year” by American Physical Society). Developed Side-Channel-Secure (SCS-) QKD, eliminating all potential passive side-channel loopholes in sender, as well as maintaining the MDI- security in detection. Developed technologies for interference between remote independent lasers, realizing long-Distance MDI-QKD with "sending-or-not-sending" Twin-Field (SNS-TF-) QKD, achieving 1,002 km in lab fiber (world record for QKD distance), and 546 km in field deployed fiber between Jinan and Qingdao (world record for QKD distance). Collaborated using the phase-sensitive property of the TF-QKD, detecting the artificial vibration source in fiber links.
Closed the "freedom-of-choice" loophole in Bell tests using volunteer-generated "free-will" inputs. Achieving 78% system efficiency in entanglement source, enabling loophole-free Bell inequality violations. Leveraged distant celestial photons for randomness generation, pushing hidden variables back by decades. Experimental realization of device independent quantum random number generation (DI-QRNG), expansion, based on the loophole free Bell inequality violation. Built a stable DI-QRNG system to support the Randomness Beacon Service (https://randomnessbeacon.com/).
