Efficient single-atom transfer from an optical conveyor belt to a tightly confined optical tweezer
Lei Xu, Ling-Xiao Wang, Guang-Jie Chen +5
Efficient loading of single atoms into tightly confined traps is crucial for advancing quantum information processing and exploring atom-photon interactions. However, directly load…
Optimal estimation of three parallel spins with genuine and restricted collective measurements
Changhao Yi, Kai Zhou, Zhibo Hou +2
Collective measurements on identical and independent quantum systems can offer advantages in information extraction compared with individual measurements. However, little is known…
Experimental Realization of Genuine Three-copy Collective Measurements for Optimal Information Extraction
Kai Zhou, Changhao Yi, Wen-Zhe Yan +5
Nonclassical phenomena tied to entangled states are the focus of foundational studies and powerful resources in many applications. By contrast, the counterparts in quantum measurem…
Neural networks for quantum state tomography with constrained measurements
Hailan Ma, Daoyi Dong, Ian R. Petersen +2
Quantum state tomography (QST) aiming at reconstructing the density matrix of a quantum state plays an important role in various emerging quantum technologies. Recognizing the chal…
