AffiliationHRI
Abstractecycling 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.
