• Authors: Chandan Kumar, Mohak Sharma, and Shikhar Arora
• Abstract summary: We generate the resource state for teleporting unknown coherent and squeezed vacuum states using two distinct strategies. We show that either of the two strategies could be beneficial depending on the type of the non-Gaussian operation, initial squeezing of the TMSV state, and the parameters characterizing the noisy channel.

• Abstract: We explore the relative advantages in continuous-variable quantum teleportation when non-Gaussian operations, namely, photon subtraction, addition, and catalysis, are performed before and after interaction with a noisy channel. We generate the resource state for teleporting unknown coherent and squeezed vacuum states using two distinct strategies: (i) Implementation of non-Gaussian operations on TMSV state before interaction with noisy channel, (ii) Implementation of non-Gaussian operations after interaction of TMSV state with noisy channel. The results show that either of the two strategies could be beneficial than the other depending on the type of the non-Gaussian operation, initial squeezing of the TMSV state, and the parameters characterizing the noisy channel. This strategy can be utilized to effectively improve the efficiency of various non-Gaussian continuous variable quantum information processing tasks.

We also observe that incremental advantage provided by performing these non-Gaussian operations on the TMST state is considerably higher than that of performing these operations on the TMSV state.
