  We study the effect of thermal fluctuations on a probe qubit interacting with
a Bose-Einstein condensed (BEC) reservoir. The zero-temperature case was
studied in [Haikka P et al 2011 Phys. Rev. A 84 031602], where we proposed a
method to probe the effects of dimensionality and scattering length of a BEC
based on its behavior as an environment. Here we show that the sensitivity of
the probe qubit is remarkably robust against thermal noise. We give an
intuitive explanation for the thermal resilience, showing that it is due to the
unique choice of the probe qubit architecture of our model.
