Abstract Single particle resolution is a requirement for numerous experimental protocols that emulate the dynamics of small systems in a bath.Here, we accurately resolve through atom counting the stochastic dynamics of a few sodium atoms in presence of a cold potassium cloud.This capability enables us eeboo coupons to rule out the effect of inter-species interaction on sodium atom number depileve easy clean dynamics, at very low atomic densities present in these experiments.

We study the noise sources for sodium and potassium in a common framework.Thereby, we assign the detection limits to 4.3 atoms for potassium and 0.

2 atoms (corresponding to 96% fidelity) for sodium.This opens possibilities for future experiments with a few atoms immersed in a quantum degenerate gas.
