"According to Heisenberg the world unobserved exists in a state of POTENTIA, a bundle of mere possibilities, tendencies to exist, a state of existence, in Heisenberg’s words, halfway between an idea and a thing.... Drs. J and K from UC Riverside have proposed to “uncollapse the wavefunction by undoing quantum measurements” using techniques more drastic than the quantum eraser. After a century of effort the quantum measurement problem still remains one of the great unsolved questions in physics. Drs. J and K propose to shed new light on the problem of measurement by investigating the inverse process of “unmeasurement”--uncovering the conditions under which solid ACTUALITY can be turned back into dreamy POTENTIA."
