Low-crosstalk optical addressing system for atomic qubits based on multiple objectives and acousto-optic deflectors
Yi-Long Chen, Rui-Rui Li, Ran He +6
Large-scale programmable trapped ion hardware, featuring high gate fidelity and long coherence times, is promising for realizing a practical fault-tolerant quantum computer (FTQC).…
Compression of Entanglement Improves Quantum Communication
Yu Guo, Hao Tang, Jef Pauwels +7
Shared entanglement can significantly amplify classical correlations between systems interacting over a limited quantum channel. A natural avenue is to use entanglement of the same…
Nonlocal photonic quantum gates over 7.0 km
Xiao Liu, Xiao-Min Hu, Tian-Xiang Zhu +8
Quantum networks provide a prospective paradigm to connect separated quantum nodes, which relies on the distribution of long-distance entanglement and active feedforward control of…
Secure Key from Quantum Discord
Rong Wang, Guan-Jie Fan-Yuan, Zhen-Qiang Yin +6
The study of quantum information processing seeks to characterize the resources that enable quantum information processing to perform tasks that are unfeasible or inefficient for c…
Experimental test of generalized multipartite entropic uncertainty relations
Zhao-An Wang, Bo-Fu Xie, Fei Ming +9
Entropic uncertainty relation (EUR) formulates the restriction of the inherent uncertainty of quantum mechanics from the information-theoretic perspective. A tighter lower bound fo…
Overcoming noise in quantum teleportation with multipartite hybrid entanglement
Zhao-Di Liu, Olli Siltanen, Tom Kuusela +5
Quantum entanglement and decoherence are the two counterforces of many quantum technologies and protocols. For example, while quantum teleportation is fueled by a pair of maximally…
