Fifty Years of the GKLS Master Equation: Foundations and Early Developments IJQF Weekly Papers • quant-ph updates on arXiv.org / 19h arXiv:2609.19404v1 Announce Type: new Abstract: The year 2026 marks the fiftieth anniversary of the two seminal papers in which Gorini, Kossakowski, and Sudarshan, and independently Lindblad, characterized the generators of completely positive quantum dynamical semigroups. We revisit the conceptual… Read more →

A Geometric Theory of Quantum Entanglement IJQF Weekly Papers • quant-ph updates on arXiv.org / 19h arXiv:2609.11720v1 Announce Type: new Abstract: Entanglement Distance (ED) was originally proposed as a geometric measure of entanglement derived from the Fubini-Study metric on the projective Hilbert space. Independently, the Meyer-Wallach and Scott measures quantify multipartite entanglement via linear entropy. In this work, we demonstrate… Read more →

Redesigning quantum theory IJQF Weekly Papers • quant-ph updates on arXiv.org / 19h arXiv:2609.03333v1 Announce Type: new Abstract: QBism understands quantum mechanics to be probability theory supplemented by additional nonclassical coherence conditions. In this dissertation, we develop these nonclassical coherence conditions from first principles, emphasizing the role of a well chosen reference measurement. After treating standard probability on subjective Bayesian lines, we… Read more →
