Operational Concealment of Measurement Incompatibility by Quantum Channels: Rank Loss versus Contraction
Mohd Asad Siddiqui, Zizhu Wang
Quantum measurements can remain incompatible yet become impossible to certify when all probe states first pass through a quantum channel. We formulate this loss of certifiability a…

Experimental Characterization of Quantumness Using the Uncertainty Principle, Coherence, and Nonlocality
Yan-Han Yang, Xin-Zhu Liu, Xing-Zhou Zheng +6
Heisenberg's uncertainty principle, coherence and Bell nonlocality have been individually examined through many experiments. In this Letter, we systematically characterize all of t…

Practical Advantage of Classical Communication in Entanglement Detection
Wen-Bo Xing, Min-Yu Lv, Lingxia Zhang +9
Entanglement is the cornerstone of quantum communication, yet conventional detection relies solely on local measurements. In this work, we present a unified theoretical and experim…
