Popis:	Measurements remain as an interesting topic of research since the formulation of quantum theory. Attempts to model quantum measurements by unitary processes are prone to various foundational issues. Here, it is proposed that measurement devices can be modelled to have an open decoherence dynamics that is faster than any other relevant timescale, which is referred to as the ultradecoherence limit. In this limit, it is shown that the clicking rate of measurement devices can be derived from its underlying parameters, not only for the von Neumann ideal measurement devices but also for photon detectors in equal footing. This study offers a glimpse into the intriguing physics of measurement processes in quantum mechanics, with many aspects open for further investigation. Comment: 7 pages, 0 figures
