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

Jul 26, 2017 · The quantum fluctuation has become a classical object upon attaining such dizzying growth: the wavefunction undergoes decoherence once it surpasses the causal limit …

Aug 14, 2025 · Actual physicists: to discuss decoherence (this requires understanding at least undergrad physics). The popular physics route is very bad because Schrödinger's cat taken in …

Sep 7, 2025 · According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference …

May 11, 2019 · The following formulation in terms of 7 basic rules of quantum mechanics was agreed upon among the science advisors of Physics Forums.

Jun 2, 2025 · The core observation is correct: supercurrents persist for months or years, while standard decoherence theory (Caldeira-Leggett) predicts collapse in nanoseconds. This 10⁶× …

Dec 18, 2011 · Yes, decoherence doesn't collapse the state, but no, decoherence irreversibly converts quantum behaviour (additive probability amplitudes) to classical behaviour (additive …

Aug 21, 2004 · Decoherence can be also controlled whith sequences of pulses, but that´s still too difficult for me. I´m working on it. It´s the optical analogous of the NMR multipulse thechniques.

Nov 26, 2017 · Forgive my novice question; but, how does one explain the fact that decoherence doesn't contradict the evolution of the wavefunction in every world? Meaning, how is causality …

Oct 31, 2019 · The splitting happens only due to decoherence governed by the Schrodinger equation. ... and, the "splitting" is going on continually, millions of times per second in the …
