  In our work, we compare three teleportation protocols: the original protocol,
the photon subtraction protocol, and the protocol with a cubic phase gate. We
evaluate the fidelity of each protocol using the example of teleportation of
the squeezed state and the Schrodinger's cat state. We show that, under equal
conditions, the teleportation scheme with a cubic phase gate achieves
significantly higher fidelity than the other protocols considered.
