Teleportation protocols with non-Gaussian operations: Conditional photon subtraction versus cubic phase gate
E. R. Zinatullin, S. B. Korolev, T. Yu. Golubeva · Physical Review A · 2023
In our paper, 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 Schr\"odinger 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.
