We study information-disturbance trade-off in generalized entanglement swapping protocols wherein starting from Bell pairs $\left(1, 2\right)$ and $\left(3, 4\right)$, one performs an arbitrary joint measurement on $\left(2, 3\right)$, so that $\left(1, 4\right)$ now becomes correlated.

We investigate the possibility of multiple use of a single copy of three-qubit states for genuine tripartite Einstein-Podolsky-Rosen (EPR) steering.
