Lensing and enhanced single atom detection via a single-pixel nanostructure
Ling-Xiao Wang, Lei Xu, Ai-Ping Liu +7
We propose and demonstrate a general mechanism for nanoscale lensing based on the phase gradient imposed by a single nanostructure scattering light in its near-field. We verify thi…
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…
Experimental Demonstration of Inequivalent Mutually Unbiased Bases
Wen-Zhe Yan, Yunting Li, Zhibo Hou +4
Quantum measurements based on mutually unbiased bases (MUB) play crucial roles in foundational studies and quantum information processing. It is known that there exist inequivalent…
Minimum-consumption discrimination of quantum states via globally optimal adaptive measurements
Boxuan Tian, Wenzhe Yan, Zhibo Hou +3
Reducing the average resource consumption is the central quest in discriminating non-orthogonal quantum states for a fixed admissible error rate . The globally optimal…
Resource Theory of Imaginarity: New Distributed Scenarios
Kang-Da Wu, Tulja Varun Kondra, Carlo Maria Scandolo +5
The resource theory of imaginarity studies the operational value of imaginary parts in quantum states, operations, and measurements. Here we introduce and study the distillation an…
