11. It has been pointed out that the heteronuclear loss rates are not reciprocal, i.e., one cannot a priori assume β i, j ′ = β j, i ′.

17. The Geiger mode can be used only for photon rates which are smaller than the inverse dead time of 1/35 ns of the APD. Considering the corresponding detection setups the count rates of Rb and Cs are 10 8 /s and 10 5 /s, respectively, thus only allowing to operate the Cs APD in the Geiger mode.
18. For Rb atom numbers less than 700 the statistics is much less, and we average over about 50 traces only. However, this does not influence the analysis of the Rb-Cs interaction parameter, because this is based only on data sets with Rb atom numbers larger than or equal to 1000.
19. While in steady state the histograms are expected to follow a Poissonian distribution, we find that also for non-steady-state conditions our data are very well described by a Poissonian. For simplicity we therefore fit a Poissonian distribution to the data and extract its mean atom number which is shifted toward smaller values for an increasing number of Rb atoms.
