Uncollapsing the wavefunction
arXiv:0708.0365
Abstract
The undoing of quantum measurements is discussed in the broader context of irreversibility in physics. We give explicit examples of how a wavefunction can be uncollapsed in two solid-state experimental set-ups. Wavefunction uncollapse shows the quantum observer paradox in a new and significantly clearer way.
