Bell nonlocality with directly generated telecom-band spin-photon entanglement
Dong-Yu Huang, Jian Wang, Xiao-Long Zhou +8
Quantum nonlocality, typically revealed through entanglement distribution across quantum networks, is a cornerstone of quantum information science. Long-distance distribution of en…
High-yield engineering and identification of oxygen-related modified divacancies in 4H-SiC
Qi-Cheng Hu, Ji-Yang Zhou, Shuo Ren +9
Modified divacancies in the 4H polytype of silicon carbide (SiC) exhibit enhanced charge stability and spin addressability at room temperature, making them attractive for quantum a…
Coherent Spin-Photon Interface of single PL6 Color Centers in Silicon Carbide
Zhen-Xuan He, GergÅ Thiering, Rui-Jian Liang +10
The PL6 color center in silicon carbide has recently emerged as a promising platform for quantum information processing, yet its coherent spin--photon interface has remained largel…
Decoherence-protected entangling gates in a silicon carbide quantum node
Shuo Ren, Rui-Jian Liang, Zhen-Xuan He +8
Solid-state color centers are promising candidates for nodes in quantum network architectures. However, realizing scalable and fully functional quantum nodes, comprising both proce…
3D imaging of the biphoton spatiotemporal wave packet
Yang Xue, Ze-Shan He, Hao-Shu Tian +6
Photons are among the most important carriers of quantum information owing to their rich degrees of freedom (DoFs), including various spatiotemporal structures. The ability to char…
Experimental Certification of Quantum Measurements with Maximally Mixed States
Jia-He Liang, Ze-Yan Hao, Jia-Kun Li +6
So far, certifying quantum devices from their input-output statistics, under minimal assumptions, required the preparation of specific pure quantum states. Recently, Xu et al. [Phy…
