  How best one can recycle a given quantum resource, mitigating the various
difficulties involved in its preparation and preservation, is of considerable
importance for ensuring efficient applications in quantum technology. Here we
demonstrate quantitatively the resource theoretic advantage of reusing a single
copy of a two-qubit entangled state towards information processing. To this
end, we consider a scenario of sequential entanglement detection of a given
two-qubit state by multiple independent observers on each of the two spatially
separated wings. In particular, we consider equal numbers of sequential
observers on the two wings. We first determine the upper bound on the number of
observers who can detect entanglement employing suitable entanglement witness
operators. In terms of the parameters characterizing the entanglement consumed
and the robustness of measurements, we then compare the above scenario with the
corresponding scenario involving multiple pairs of entangled qubits shared
among the two wings. This reveals a clear resource theoretic advantage of
recycling a single copy of a two-qubit entangled state in the sequential
network.
