Expectation-Realization Interpretation of Quantum Superposition IJQF Weekly Papers • quant-ph updates on arXiv.org / 10h arXiv:2511.04154v1 Announce Type: new Abstract: By comparing Schr\”odinger’s cat with its classical counterpart, I show that a quantum superposition should be understood as an expectation over possible eigenstates weighted by wave-like probabilities. Upon the occurrence of a certain event, the quantum system is randomly realized into one… Read more →

Entanglement and Thermodynamic Scaling Laws in Quantum Superabsorption IJQF Weekly Papers • quant-ph updates on arXiv.org / 11h arXiv:2510.26373v1 Announce Type: new Abstract: Quantum batteries (QBs) exploit collective quantum resources to surpass the limits of classical energy storage and power delivery. We analyze $N$-qubit cavity-coupled QBs governed by Dicke and Tavis–Cummings models under Gaussian driving and open-system dynamics. Finite-size scaling laws $\mathcal{O}(N)\!\sim\!N^{\alpha}$… Read more →

Quantum mysteries explained in digestible form IJQF Weekly Papers • quant-ph updates on arXiv.org / 13h arXiv:2510.20144v1 Announce Type: new Abstract: Years ago, Itamar Pitowski asked two relevant questions: Why microphysical (quantum) phenomena and classical phenomena differ in the way they do? and, what kind of explanation could qualify as a reasonable one? I argue that both questions can be answered by… Read more →

Universal Growth of Krylov Complexity Across A Quantum Phase Transition IJQF Weekly Papers • quant-ph updates on arXiv.org / 11h arXiv:2510.13947v1 Announce Type: new Abstract: We study the statistical properties of the spread complexity in the Krylov space of quantum systems driven across a quantum phase transition. Using the diabatic Magnus expansion, we map the evolution to an effective one-dimensional hopping model…. Read more →

Stochastic interpretation of quantum mechanics IJQF Weekly Papers • quant-ph updates on arXiv.org / 22h arXiv:2510.06418v1 Announce Type: new Abstract: We express the probabilistic character associated to the wave function by treating it as a stochastic variable. This is accomplished by means of a stochastic equation for the wave function whose noise changes the phase of the wave function but not its… Read more →

Quantum Signatures of Strange Attractors IJQF Weekly Papers • quant-ph updates on arXiv.org / 13h arXiv:2510.01416v1 Announce Type: new Abstract: In classical mechanics, driven systems with dissipation often exhibit complex, fractal dynamics known as strange attractors. This paper addresses the fundamental question of how such structures manifest in the quantum realm. We investigate the quantum Duffing oscillator, a paradigmatic chaotic system, using… Read more →

Quantum statistical mechanical gauge invariance IJQF Weekly Papers • quant-ph updates on arXiv.org / 13h arXiv:2509.20494v1 Announce Type: new Abstract: We address gauge invariance in the statistical mechanics of quantum many-body systems. The gauge transformation acts on the position and momentum degrees of freedom and it is represented by a quantum shifting superoperator that maps quantum observables onto each other. The shifting… Read more →

Open-system analogy of Berry conjecture IJQF Weekly Papers • quant-ph updates on arXiv.org / 13h arXiv:2509.14644v1 Announce Type: new Abstract: Berry conjecture is central to understanding quantum chaos in isolated systems and foundational for the eigenstate thermalization hypothesis. Here we establish an open-system analogy of the Berry conjecture, connecting quantum steady states to classical dissipative attractors in the semiclassical limit. We demonstrate… Read more →

Retrocausal capacity of a quantum channel IJQF Weekly Papers • quant-ph updates on arXiv.org / 13h arXiv:2509.08965v1 Announce Type: new Abstract: We study the capacity of a quantum channel for retrocausal communication, where messages are transmitted backward in time, from a sender in the future to a receiver in the past, through a noisy postselected closed timelike curve (P-CTC) represented by the… Read more →

Quantum aspects of the classical Maxwell’s equations in free space from the perspective of the correspondence principle IJQF Weekly Papers • quant-ph updates on arXiv.org / 1d arXiv:2509.02620v1 Announce Type: new Abstract: Due to the advent of Quantum Mechanics’ 100th anniversary, we wrote this review paper in order to present a discussion that addresses the foundations of this theory. And since the… Read more →

Symmetry enforces entanglement at high temperatures IJQF Weekly Papers • quant-ph updates on arXiv.org / 17h arXiv:2508.20166v1 Announce Type: new Abstract: Many-body quantum systems with local interactions undergo “sudden death of entanglement” at high temperatures, whereby thermal states become classical mixtures of product states. We investigate whether symmetry constraints can prevent this phenomenon. We prove that strongly symmetric thermal states (canonical ensemble)… Read more →
