Microwave electrometry via electromagnetically induced absorption in cold Rydberg atoms
Kai-Yu Liao, Hai-Tao Tu, Shu-Zhe Yang +6
The atom-based traceable standard for microwave electrometry shows promising advantages by enabling stable and uniform measurement. Here we theoretically propose and then experimen…
Demonstration of the quantum principle of least action with single photons
Yong-Li Wen, Yunfei Wang, Li-Man Tian +5
The principle of least action is arguably the most fundamental principle in physics as it can be used to derive the equations of motion in various branches of physics. However, thi…
Proposal for implementing universal superadiabatic geometric quantum gates in nitrogen-vacancy centers
Zhen-Tao Liang, Xianxian Yue, Qingxian Lv +4
We propose a feasible scheme to implement a universal set of quantum gates based on geometric phases and superadiabatic quantum control. Consolidating the advantages of both strate…
Approaching the standard quantum limit of a Rydberg-atom microwave electrometer
Hai-Tao Tu, Kai-Yu Liao, Guo-Dong He +7
The development of a microwave electrometer with inherent uncertainty approaching its ultimate limit carries both fundamental and technological significance. Recently, the Rydberg…
Semi-supervised Graph Anomaly Detection via Robust Homophily Learning
Guoguo Ai, Hezhe Qiao, Hui Yan +1
Semi-supervised graph anomaly detection (GAD) utilizes a small set of labeled normal nodes to identify abnormal nodes from a large set of unlabeled nodes in a graph. Current method…
Increase the Efficiency of Post-selection in Direct Measurement of Quantum Wave Function
Yong-Li Wen, Shanchao Zhang, Hui Yan +1
Direct weak or strong measurement of quantum wave function has been demonstrated based on the post-selection; however, the efficiency of the measurement is greatly limited by the s…
