  We show that there exist Gaussian channels which are amendable. A channel is
amendable if when applied twice is entanglement breaking while there exists a
unitary filter such that, when interposed between the first and second action
of the map, prevents the global transformation from being entanglement breaking
[Phys. Rev. A 86, 052302 (2012)]. We find that, depending on the structure of
the channel, the unitary filter can be a squeezing transformation or a phase
shift operation. We also propose two realistic quantum optics experiments where
the amendability of Gaussian channels can be verified by exploiting the fact
that it is sufficient to test the entanglement breaking properties of two mode
Gaussian channels on input states with finite energy (which are not maximally
entangled).
