Query: Bidirectional Teleportation using Fisher Information   In this contribution, we reformulated the bidirectional teleportation
protocol suggested in [7], by means of Bloch vectors as well as the local
operations are represented by using Pauli operators. Analytical and numerical
calculations for the teleported state and Fisher information are introduced. It
is shown that both quantities depend on the initial state settings of the
teleported qubits and their triggers. The Fidelities and the Fisher information
of the bidirectionally teleported states are maximized when the qubit and its
trigger are polarized in the same direction. The minimum values are predicted
if both initial qubits have different polarization or non-zero phase. The
maximum values of the Fidelity and the quantum Fisher information are the same,
but they are predicted at different polarization angles. We display that the
multi-parameter form is much better than the single parameter form, where it
satisfies the bounds of classical, entangled systems and the uncertainty
principle.
