We address the recently posed question as to whether the nonlocality of asingle member of an entangled pair of spin $1/2$ particles can be shared amongmultiple observers on the other wing who act sequentially and independently ofeach other [1]. We first show that the optimality condition for the trade-offbetween information gain and disturbance in the context of weak or non-idealmeasurements emerges naturally when one employs a one-parameter class ofpositive operator valued measures (POVMs). Using this formalism we then proveanalytically that it is impossible to obtain violation of theClauser-Horne-Shimony-Holt (CHSH) inequality by more than two Bobs in one ofthe two wings using unbiased input settings with an Alice in the other wing.

Sharing of Nonlocality of a single member of an Entangled Pair Is Not Possible by More Than Two Unbiased Observers on the other wing
