	Quantum measurements not only extract information but also reshape quantum states through measurement backaction, thereby determining how quantum resources can be distributed and recycled. In this talk, recent progress on the sequential sharing of quantum correlations will be reviewed from the perspective of generalized quantum measurements and quantum instruments. Particular emphasis will be placed on Bell nonlocality, EPR steering, entanglement, network nonlocality, and contextuality under sequential and weak-measurement scenarios. Recent advances on complementarity-based correlation sharing and unified measurement frameworks beyond conventional POVM descriptions will also be discussed, highlighting how different Kraus structures govern resource dissipation, robustness, and quantum resource recycling in multipartite and sequential quantum information protocols.
