Modelling quantum measurements without superposition

arXiv:2602.17462v1 Announce Type: new Abstract: Superposition is the core feature that sets quantum theory apart from classical physics. Here, we investigate whether sets of quantum measurements can be modelled by using only devices that are operationally classical, in the sense that they have no superposition properties. This leads us to propose classical measurement models, which we show to be s

arXiv:2512.09950v3 Announce Type: replace-cross Abstract: What does “Big Bang” mean? What was the actual origin of these two words? There are many aspects hidden under this name, which are seldom explained. They are discussed here. To frame the analysis, help will be sought from the highly authoritative voices of two exceptional writers: William Shakespeare and Umberto Eco. Both have explored the

arXiv:2602.14601v1 Announce Type: new Abstract: We explain the achievements that were awarded 2022 Nobel Prize in Physics, as well as the preceding and the later developments. The main notions and historic cornerstones of Bell inequalities, the related researches on quantum entanglement are reviewed, and the key physical ideas are emphasized. Among the early work, C. S. Wu’s contributions using po

arXiv:2602.14059v1 Announce Type: new Abstract: I discuss the physical basis of classical mechanics, such as expressed commonly using the framework of Newton’s Principia. Newton’s formulation of the laws of motion is seen to have quite a few ambiguities and shortcomings. Therefore I offer an alternative set of laws, based in particular on ideas of his contemporaries Huygens and Leibniz with a cruc

arXiv:2602.13708v1 Announce Type: new Abstract: Symmetry is often treated in philosophy of physics as an interpretive problem. A particularly lively dispute concerns local symmetries: do they indicate surplus structure that ought to be expunged, or are they merely a harmless redundancy? One influential response favours the second option for certain theories — those dubbed internally sophisticated

arXiv:2602.16495v1 Announce Type: cross Abstract: We critically examine proposals for the so-called warp-drive spacetimes and classify these models based on their various restrictions within the framework of General Relativity. We then provide a summary of general formalism for each class, and in the process, we highlight some misconceptions, misunderstandings, and errors in the literature that ha

arXiv:2506.16480v5 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:2602.16985v1 Announce Type: cross Abstract: In his late piece ‘La nouvelle cuisine’ (Bell 1990), John Bell describes the steps from an intuitive, informal principle of locality to a mathematical rule called Factorizability. This rule stipulates that when possible past causes are held fixed, the joint probabilities of outcomes of spacelike separated measurements, conditional on measurement se
