Query: Quantum Zeno and Anti-Zeno Effects on the Entanglement Dynamics of
  Qubits Dissipating into a Common and non-Markovian Environment   We investigate the quantum Zeno and anti-Zeno effects on pairwise
entanglement dynamics of a collective of non-interacting qubits which have been
initially prepared in a Werner state and are off-resonantly coupled to a common
and non-Markovian environment. We obtain the analytical expression of the
concurrence in the absence and presence of the non-selective measurements. In
particular, we express our results in the strong and weak coupling regimes and
examine the role of the system size, and the effect of the detuning from the
cavity field frequency on the temporal behaviour of the pairwise entanglement.
We show that, the detuning parameter has a positive role in the protection of
entanglement in the absence of the measurement for weak coupling regime. We
find that for the values of detuning parameter less than the cavity damping
rate, the quantum Zeno effect is always dominant, while for the values greater
than the cavity damping rate, both Zeno and anti-Zeno effects can occur,
depending on the measurement intervals. We also find that the anti-Zeno effect
can occur in the pairwise entanglement dynamics in the absence and presence of
the detuning in the strong coupling regime.
