"The characteristic feature of the first (often called ‘dynamical’ or ‘environmental’ decoherence) is the study of concrete models of (spontaneous) interactions between a system and its environment that lead to suppression of interference effects" http://plato.stanford.edu/entries/qm-decoherence/ This seems to raise a problem since environmental surroundings are a fact even before an observer looks on the electron.(it is located in a room e.t.c). so were do we draw the line when decoherence comes into the picture? has it to do with the <distance> of the environmental influence and the electron? Decoherence seems to have a problem since there always exists an environment surrounding regardless of a human observer or a camera filming it. And yet the suppresion only occurs when we actually look at it closely(or put a camera in the room) How is this solved?
