Single Particles
According to proponents of this interpretation, no single system is ever required to be postulated to exist in a physical mixed state so the state vector does not need to collapse.
It can also be argued that this notion is consistent with the standard interpretation in that, in the Copenhagen interpretation, statements about the exact system state prior to measurement can not be made. That is, if it were possible to absolutely, physically measure say, a particle in two positions at once, then quantum mechanics would be falsified as quantum mechanics explicitly postulates that the result of any measurement must be a single eigenvalue of a single eigenstate.

“...Advertising companies hire the very brightest, wittiest young people to write for them. Not one single sentence of it is worth repeating. Why? Because it wasn’t meant.”

“The atoms of Democritus
And Newton’s particles of light
