Uncollapsing the wavefunction

TL;DR

This paper explores the concept of reversing quantum measurements, demonstrating how wavefunctions can be uncollapsed in solid-state experiments, thereby clarifying the quantum observer paradox.

Contribution

It provides explicit experimental examples of wavefunction uncollapse, advancing understanding of quantum measurement reversibility.

Findings

Wavefunction uncollapse demonstrated in solid-state setups

Reversibility of quantum measurements shown experimentally

Clarifies the quantum observer paradox

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.
