Teleportation protocols with non-Gaussian operations: conditional photon subtraction versus cubic phase gate

E. R. Zinatullin, S. B. Korolev, T. Yu. Golubeva

英文摘要:

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.
