No, because decoherence does not explain why measurements have single outcomes. It only explains why there is no interference between different outcomes.timmdeeg said:The decoherence time is extremely short for macroscopic objects like a detector. Does this mean that the outcome of a quantum measurement which happens instantaneous can be understood as being caused by decoherence?
The detector may be large, but what is important is how much influence a measurement has on the state of the detection system. A detector that captures a photon or other particle without disturbing its spin would not result in decoherence of the spin. Once a measurement has resulted in the movement of a dial or the recording or transmission of measurement data, that measured state is committed - it can be "understood" as decohered.timmdeeg said:The decoherence time is extremely short for macroscopic objects like a detector.
