Experimental mode-pairing measurement-device-independent quantum key distribution without global phase-locking
Hao-Tao Zhu, Yizhi Huang, Hui Liu +11
In the past two decades, quantum key distribution networks based on telecom fibers have been implemented on metropolitan and intercity scales. One of the bottlenecks lies in the ex…
Experimental Simulation of Larger Quantum Circuits with Fewer Superconducting Qubits
Chong Ying, Bin Cheng, Youwei Zhao +14
Although near-term quantum computing devices are still limited by the quantity and quality of qubits in the so-called NISQ era, quantum computational advantage has been experimenta…
Portable ground stations for space-to-ground quantum key distribution
Ji-Gang Ren, Maimaiti Abulizi, Hai-Lin Yong +23
Quantum key distribution (QKD) uses the fundamental principles of quantum mechanics to share unconditionally secure keys between distant users. Previous works based on the quantum…
113 km Free-Space Time-Frequency Dissemination at the 19th Decimal Instability
Qi Shen, Jian-Yu Guan, Ji-Gang Ren +28
Optical clock networks play important roles in various fields, such as precise navigation, redefinition of "second" unit, and gravitational tests. To establish a global-scale optic…
Loss-tolerant all-photonic quantum repeater with generalized Shor code
Rui Zhang, Li-Zheng Liu, Zheng-Da Li +7
The all-photonic quantum repeater (APQR) is a promising repeater scheme to realize long-distance quantum communication. For a practical APQR, an indispensable requirement is the ro…
Realization of fast all-microwave CZ gates with a tunable coupler
Shaowei Li, Daojin Fan, Ming Gong +29
The development of high-fidelity two-qubit quantum gates is essential for digital quantum computing. Here, we propose and realize an all-microwave parametric Controlled-Z (CZ) gate…
