Local predictability and coherence versus distributed entanglement in
  entanglement swapping from partially entangled pure states
Complete complementarity relations, as e.g. $P(\rho_{A})^{2} +
C(\rho_{A})^{2} + E(|\Psi\rangle_{AB})^{2}=1$, constrain the local
predictability, $P$, and local coherence, $C$, and the entanglement, $E$, of
bipartite pure states. For pairs of qubits prepared initially in a particular
class of partially entangled pure states with null local coherence, these
relations were used in Ref. [Phys. Lett. A, 451, 128414 (2022)] to provide an
operational connection between local predictability of the pre-measurement
states with the probability of the maximally entangled components of the states
after the Bell-basis measurement of the entanglement swapping protocol (ESP).
In this article, we extend this result for general pure initial states
establishing the relation between $P$, $C$ and the distributed entanglement in
the ESP. We use IBM's quantum computers to verify experimentally some instances
of these general theoretical results.
