Abstract | ecycling qubits of entangled state for sharing non-locality through the quantum violation of Clauser-Horne- Shimony-Halt inequality is the area of recent interest. It has been shown that by recycling both component of shared two qubit entangled state, non-locality can be shown for first pair of observers but cannot be shared by other independent sequential pair of observers. In this work, we study the sharing of non-locality and non- trivial preparation contextuality by recycling both component of n-bit entangled state. For this, we consider the quantum violation of a family of Bell’s inequalities for two party say, Alice and Bob performing 2^(n-1) and n measurements of dichotomic observables, respectively. First, we show that non-locality can be shared only by first pair of observers through the quantum violation of local bound of family of Bell’s inequalities for n-bit case. Further, using the quantum violation of preparation non-contextual bound of same family of Bell’s inequalities, we show that non-trivial preparation contextuality can be generated for arbitrary pair of independent sequential observers on both sides.
