Jul 29, 2020 · Decoherence does not eliminate quantum coherence, as demonstrated in a modified Wigner's Friend experiment. The study shows that even when Wigner's Friend experiences …

Jan 5, 2018 · Question (1): will the fact that the photons entangled with that matter destroy the interference pattern? I suspect it might, since I think (think) the reason why large molecules (larger …

Jun 2, 2023 · Questions about decoherence vs. observer wave function collapse and multi-worlds interpretation. Am I right that Zeh's decoherence theory does not involve an observer, and esp not a …

Dec 3, 2022 · Bam, decoherence (well, at least if we call the second particle the "environment"). This can also be noticed in the reduced density matrix, where the off-diagonal elements are now zero. But …

Apr 17, 2024 · Decoherence is a unitary process that transforms coherent wave functions into incoherent mixtures through entanglement with environmental degrees of freedom. It is distinct from …

Jul 13, 2024 · TL;DR Summary How do time dilation and decoherence cause apparent information loss? Is perceived information loss in high decoherence environments due to faster information transfer, …

Oct 29, 2023 · Decoherence is described as the process that leads to the apparent "splitting" of worlds, where interactions with the environment irreversibly disseminate information about quantum states. …

Mar 21, 2009 · Study the effects of decoherence on quantum systems and its role in measurement outcomes. Explore advanced quantum mechanics topics, including the mathematical formalism of …

Dec 13, 2009 · I don't think this is a problem anymore. Decoherence makes the density matrix of the combined system (the one being measured and its environment) diagonal in somebasis, which is …

Jul 18, 2014 · Hi, I was wondering whether we are sure (I know, strong word) that decoherence is the mechanism that takes us from the quantum world to our classical world. Correct me if I'm wrong, but …
