Optimal finite-copy readout of three-qubit entanglement with state retention
Yu-Xin Wu, Yuan-Hong Tao, Ji-Hui Mo +3
For unknown three-qubit pure states, we characterize the optimal trade-off among GHZ-class certification, binary probability readout of the three-tangle, and conditional state rete…
Pairwise detection, chiral conversion: Resource theory of quantum multistates
Yuan-Hong Tao, Yu-Xin Wu, Bing Xie +1
Basis-independent coherence of a quantum multistate is fixed by whether its constituent states commute, and for qubits it is detected by pairwise state overlaps alone. What governs…
Wave-Particle-Mixedness Relationships Based on lp-norm Coherence
Wei-Ning Li, Ming Fang, Yuan-Hong Tao +2
We investigate the relationships among the wave property, particle property and mixedness of quantum states based on the lp-norm coherence. By conforming that the lp-norm coherence…
Violation of Svetlichny's inequality in a system of spins
Yang Xiang, Yuan Tao
Quantum multi-particle correlations are one of the most intriguing properties of quantum entanglement, arising from collective entangled states of multiple particles. Svetlichny's…
Bargmann-invariant framework for local unitary equivalence and entanglement
Lin Zhang, Bing Xie, Yuanhong Tao
Research on quantum states often focuses on the correlation between nonlocal effects and local unitary invariants, among which local unitary equivalence plays a significant role in…
The uncertainty of quantum states with respect to the projective measurement
Ming-Jing Zhao, Yuanhong Tao
The uncertainty relation is a distinctive characteristic of quantum theory. The uncertainty is essentially rooted in quantum states. In this work we regard the uncertainty as an in…
