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.

Famous quotes containing the words single and/or particles:
“A single gentle rain makes the grass many shades greener. So our prospects brighten on the influx of better thoughts.”
—Henry David Thoreau (1817–1862)
“In another’s sentences the thought, though it may be immortal, is as it were embalmed, and does not strike you, but here it is so freshly living, even the body of it not having passed through the ordeal of death, that it stirs in the very extremities, and the smallest particles and pronouns are all alive with it. It is not simply dictionary it, yours or mine, but IT.”
—Henry David Thoreau (1817–1862)
