Programmable Rapid Adiabatic Passage laser pulses for Ultra-fast Gates on trapped ions
En-Teng An, Hao-Qing Zhang, Yun-Feng Huang +2
Scalable quantum gates remain a central challenge for trapped-ion quantum computing. Ultrafast gates driven by spin-dependent kicks (SDKs) provide a promising approach. However, cu…
Experimental violation of a Bell-like inequality for causal order
Yu Guo, Hao Tang, Bo-Xuan Wang +9
Quantum mechanics is compatible with scenarios where physical processes happen in an indefinite order. In theory, this feature could be detected through violations of inequalities…
Experimental genuine quantum nonlocality in the triangle network
Ning-Ning Wang, Chao Zhang, Huan Cao +8
In the last decade, it was understood that quantum networks involving several independent sources of entanglement which are distributed and measured by several parties allowed for…
Experimental observation of entropic-singularity-induced nonadditive quantum communication in a qutrit platypus channel
Yu Guo, Bo-Xuan Wang, Xiao-Min Hu +4
The nonadditivity of channel capacity is a defining feature that distinguishes quantum communication from classical communication. In the quantum realm, the channel capacity is det…
A Metropolitan-scale Multiplexed Quantum Repeater with Bell Nonlocality
Tian-Xiang Zhu, Chao Zhang, Zhong-Wen Ou +7
Quantum repeaters can overcome exponential photon loss in optical fibers, enabling heralded entanglement between distant quantum memories. The definitive benchmark for this entangl…
Binarisation-loophole-free observation of high-dimensional quantum nonlocality
Jia-le Miao, Elna Svegborn, Zhuo Chen +7
Bell inequality tests based on high-dimensional entanglement usually require measurements that can resolve multiple possible outcomes. However, the implementation of high-dimension…
