  The effects of cosmological expansion on quantum bosonic states are
investigated, using quantum information theory. In particular, a generic
Bogoliubov transformation of bosonic field modes is considered and the state
change on a single mode is regarded as the effect of a quantum channel.
Properties and capacities of this channel are thus explored in the framework of
$f(Q)$ theories. As immediate result, we obtain that the information on a
single-mode state appears better preserved, whenever the number of particles
produced by the cosmological expansion is small. Hence, similarly to general
relativity, we show that analogous particle productions result even if we
consider symmetric teleparallel gravity theories. Thus, we investigate a power
law $f(Q)$ model, leaving unaltered the effective gravitational coupling, and
minimise the corresponding particle production. We thus show how to optimise
the preservation of classical and quantum information, stored in a bosonic mode
states in the remote past. Finally, we compare our findings with those obtained
in general relativity.
