Unified Framework for Quantum Resource Recycling via Instrument-Dependent Back-action
Zinuo Cai, Jianxin Song, Changliang Ren
Accurate characterization of measurement backaction is crucial for understanding the limits of reusing quantum correlations in sequential scenarios. Here, we develop a unified quan…

Complementarity Reveals Entanglement Sharing in Sequential Quantum Measurements
Zinuo Cai, Changliang Ren
We investigate entanglement sharing in a two-qubit sequential measurement scenario using three complementary classical correlation metrics: mutual information (I), sum of condition…

Sharing Quantum Steering via Standard Projective Measurements
Shufen Dong, Zinuo Cai, Chunfeng Wu +1
We propose a scheme for the sharing of quantum steering among three observers, Alice, Bob, and Charlie using standard projective measurements. We show that in the unilateral sequen…
