No if the Collapse of the wavefunction is not a real thing decoherence have to be a part of the nature of the wavefunction that we do not know how to describe right now and then when we say that we measure a particle we are just interacting with it in a maner that the decoherense in the wavefunction constraints it to a smaler space of possible states and the wavefunction is exactly as complex and difficult to simulate is it was when it was in a superposition state
