Abstract: We attempt to clarify certain puzzles concerning state collapse. In open quantum systems decoherence is a necessary consequence of the transfer of information to the outside; we prove an upper bound for the amount of coherence which can survive such a transfer. In large closed systems decoherence is not observed, but we will show that it is usually harmless to assume its occurrence. An independent physical collapse mechanism over and above Schrödinger's equation and the probability interpretation of quantum states is therefore redundant.
