- Abstract: While photon catalyzed two mode squeezed vacuum state has been considered in
context of quantum teleportation, similar studies have not been yet conducted
for photon catalyzed two-mode squeezed thermal (TMST) state. This can be
attributed to challenges involved in the evaluation of teleportation fidelity
for photon catalyzed TMST state. In this article, we consider a practical
scheme for the implementation of non-Gaussian operation, viz., photon
subtraction, photon addition, and photon catalysis, on TMST state. The
generated states are employed as resources in continuous-variable quantum
teleportation. The results show that the three non-Gaussian operations can
enhance the teleportation fidelity. Considering the success probability of the
non-Gaussian operations, we identify single-photon catalysis and single photon
subtraction to be optimal for teleporting input coherent states, at low and
intermediate squeezing levels.

Bosonic quantum error correcting codes are primarily designed to protect against single-photon loss.
Error correction requires a recovery operation that maps the error states -- which have opposite parity -- back onto the code states.
Here, we realize a collection of photon-number-selective, simultaneous photon addition operations on a bosonic mode.
