Free-Space Twin-Field Quantum Key Distribution
Yu-Huai Li, Ting Zeng, Min-Yan Wang +22
Twin-field quantum key distribution (TF-QKD) elevates the secure key rate from a linear to a square-root dependence on channel loss while preserving measurement-device-independent…
Quantum Random Number Generation with Uncharacterized Laser and Sunlight
Yu-Huai Li, Xuan Han, Yuan Cao +8
The entropy or randomness source is an essential ingredient in random number generation. Quantum random number generators generally require well modeled and calibrated light source…
Field demonstration of distributed quantum sensing without post-selection
Si-Ran Zhao, Yu-Zhe Zhang, Wen-Zhao Liu +12
Distributed quantum sensing can provide quantum-enhanced sensitivity beyond the shot-noise limit (SNL) for sensing spatially distributed parameters. To date, distributed quantum se…
Chromatic interferometry with small frequency differences
Luo-Yuan Qu, Lu-Chuan Liu, Jordan Cotler +9
By developing a `two-crystal' method for color erasure, we can broaden the scope of chromatic interferometry to include optical photons whose frequency difference falls outside of…
Sending-or-Not-Sending with Independent Lasers: Secure Twin-Field Quantum Key Distribution Over 509 km
Jiu-Peng Chen, Chi Zhang, Yang Liu +15
Twin field quantum key distribution promises high key rates at long distance to beat the rate distance limit. Here, applying the sending or not sending TF QKD protocol, we experime…
Quantum Coherence Witness with Untrusted Measurement Devices
You-Qi Nie, Hongyi Zhou, Jian-Yu Guan +4
Coherence is a fundamental resource in quantum information processing, which can be certified by a coherence witness. Due to the imperfection of measurement devices, a conventional…
