Compact non-degenerate entangled-photon source and near-infrared-to-telecom quantum teleportation
Xu-Jie Peng, Ling-Xuan Kong, He Lu
The polarization-entangled photon source (PEPS) at non-degenerated wavelengths is pivotal to connect quantum systems working at different wavelengths, with the assistance of quantu…
High-efficiency On-chip Quantum Photon Source in Modal Phase-matched Lithium Niobate Nanowaveguide
Xiao-Xu Fang, Hao-Yang Du, Xiuquan Zhang +3
Thin-film lithium niobate on insulator~(LNOI) emerges as a promising platform for integrated quantum photon source, enabling scalable on-chip quantum information processing. The mo…
Efficient generation of broadband photon pairs in shallow-etched lithium niobate nanowaveguide
Xiao-Xu Fang, Leiran Wang, He Lu
We design and fabricate shallow-etched periodically poled lithium niobate waveguide to realize highly-efficient broadband spontaneous parametric down-conversion~(SPDC) on nanophoto…
Experimental virtual distillation of entanglement and coherence
Ting Zhang, Yukun Zhang, Lu Liu +4
Noise is in general inevitable and detrimental to practical and useful quantum communication and computation. Under the resource theory framework, resource distillation serves as a…
Experimental distillation of tripartite quantum steering with an optimal local filtering operation
Qian-Xi Zhang, Xiao-Xu Fang, He Lu
Multipartite Einstein-Podolsky-Rosen~(EPR) steering admits multipartite entanglement in the presence of uncharacterized verifiers, enabling practical applications in semi-device-in…
Quantification of Entanglement and Coherence with Purity Detection
Ting Zhang, Graeme Smith, John A. Smolin +7
Entanglement and coherence are fundamental properties of quantum systems, promising to power near future quantum technologies, such as quantum computation, quantum communication an…
