The probabilistic character of measurement processes is one of the most fascinating aspects of quantum mechanics. In many-body systems quantum noise can reveal the non-local correlations and multiparticle entanglement in the underlying states. In this talk I will review recent theoretical and experimental progress in applications of the quantum noise analysis to the study of many body states of ultracold atoms. Examples include HBT correlations and detection of magnetic phases in optical lattices, analysis of fluctuations in interference fringe contrast as a probe of prethermalization in one dimensional condensates. I will also discuss the possibility of observing dynamical Casimir effect and Unruh-type thermal correlations in dynamically split condensates.
