arXiv:2511.20792v1 Announce Type: new Abstract: The quantum Zeno effect typically refers to freezing the dynamics of a quantum system through frequent observations. In general, quantum Zeno dynamics is obtained with an error of order $\mathcal{O}(1/N)$, where $N$ is the number of projective measurements performed within a fixed evolution time. In this work, we develop higher-order Zeno sequences t
Deriving the Generalised Born Rule from First Principles

arXiv:2511.21355v1 Announce Type: new Abstract: A basic postulate of modern compositional approaches to generalised physical theories is the generalised Born rule, in which probabilities are postulated to be computable from the composition of states and effects. In this paper we consider whether this postulate, and the strength of the identification between scalars and probabilities, can be argued
The Quantum Formalism Revisited

physics.hist-ph updates on arXiv.org / 6d
arXiv:2506.16480v4 Announce Type: replace-cross Abstract: For the simple system of a point-like particle confined to a straight line, I compile, initially in a concise table, the structural elements of quantum mechanics and contrast them with those of classical (statistical) mechanics. Despite many similarities, there are the well-known fundamental differences, resulting from the algebraic non-com

arXiv:2504.10366v2 Announce Type: replace-cross Abstract: This study presents the design and the implementation of an inquiry-based reconstruction of Rutherford’s gold foil experiment. The activity engaged students in collaborative exploration using a “black box” as an analogical model of the atom. Grounded in constructivist theory and the Focus Action-Reflection (FAR) model to introduce analogies

arXiv:2511.19242v1 Announce Type: cross Abstract: Once again, dispute has arisen over the interpretation of proposed quantum information theory experiments to probe the quantum nature of gravity by testing for gravitationally induced entanglement (GIE) between two spatially separated massive particles ([1] vs. [11,12]; further contributions in [7,9]). The confusion appears to reside in interpretin
Quantum Spacetime: Echoes of basho

physics.hist-ph updates on arXiv.org / 2d
arXiv:2511.17691v1 Announce Type: new Abstract: I will discuss how the concept of basho, introduced by Nishida Kitaro nearly a century ago, can give an interesting insight to understand the concept of a point in modern quantum gravity. A quantum spacetime, necessary for the quantization of gravity, requires a whole rethinking of geometry, starting from the primitive concepts, like that of a point.
How to be an orthodox quantum mechanic

arXiv:2504.20597v3 Announce Type: replace-cross Abstract: This work sets out to answer a single question: what is the orthodox interpretation of quantum mechanics? However, we adopt a different approach to that normally used. Rather than surveying physicists, or poring over the precise details of the thoughts of Bohr and Heisenberg, we review a collection of 42 textbooks on quantum mechanics, enco
Comment on Classical-Gravity–Quantum-Matter Claims About Gravity-Mediated Entanglement

arXiv:2511.20717v1 Announce Type: cross Abstract: A recent paper by Aziz and Howl (Nature 2025) argues that, once quantum matter is described at the level of quantum field theory and coupled to a classical gravitational field, higher order processes can generate entanglement between two spatially separated masses. A contemporaneous critical note (Marletto, Oppenheim, Vedral, Wilson, arXiv:2511.073
