Device-independent quantum key distribution over 100 km with single atoms
Bo-Wei Lu, Chao-Wei Yang, Run-Qi Wang +15
Device-independent quantum key distribution (DI-QKD) is a key application of the quantum internet. We report the realization of DI-QKD between two single-atom nodes linked by 100-k…
A building block of quantum repeaters for scalable quantum networks
Wen-Zhao Liu, Ya-Bin Zhou, Jiu-Peng Chen +26
Quantum networks, integrating quantum communication, quantum metrology, and distributed quantum computing, could provide secure and efficient information transfer, high-resolution…
Metrology-grade mid-infrared spectroscopy for multi-dimensional perception
Baoqi Shi, Chenxi Zhang, Ming-Yang Zheng +11
The mid-infrared spectral window is essential for molecular fingerprinting and atmospheric sensing, yet unlocking its full potential is currently constrained by a fundamental instr…
Electrically pumped ultra-efficient quantum frequency conversion on thin film lithium niobate chip
Xina Wang, Xu-Feng Jiao, Bo Cao +5
Quantum frequency conversion (QFC) plays a crucial role in constructing seamless interconnection between quantum systems operating at different wavelengths. To advance future quant…
Realization of an untrusted intermediate relay architecture using a quantum dot single-photon source
Mi Zou, Yu-Ming He, Yizhi Huang +22
To fully exploit the potential of quantum technologies, quantum networks are needed to link different systems, significantly enhancing applications in computing, cryptography, and…
Robust quantum computational advantage with programmable 3050-photon Gaussian boson sampling
Hua-Liang Liu, Hao Su, Si-Qiu Gong +34
The creation of large-scale, high-fidelity quantum computers is not only a fundamental scientific endeavour in itself, but also provides increasingly robust proofs of quantum compu…
