Russell on Weyl’s unified field theory. (arXiv:2208.08495v1 [physics.hist-ph]) 上午10:36 | physics.hist-ph updates on arXiv.org Authors: C. Romero In 1918, H. Weyl proposed a unified theory of gravity and electromagnetism based on a generalization of Riemannian geometry. With hindsight we now could say that the theory carried with it some of the most original ideas that inspired the physics of the twentieth… Read more →

The ontological meaning of the wave function has been debated for many years. A widely-discussed view is wave function realism, according to which the wave function represents a real physical field in a fundamental high-dimensional space. In this paper, I argue that wave function realism is inconsistent with the reality of the global phase. In other words, the global phase… Read more →

Attached is our comment on the paper by Frank Lad, “Quantum Mysteries for No One” in Journal of Modern Physics (July 2021). Lad’s paper claims to refute Mermin’s result in, “Quantum Mysteries for Anyone” in Journal of Philosophy (1981). [Also published as, “Bringing home the atomic world: Quantum mysteries for anybody” in American Journal of Physics (1981).] While Lad may… Read more →
I hope that these two new results presented in arXiv:1805.03952v12 will be interesting: I have found that the process of scattering a particle on a one-dimensional delta-potential (and any other short-range potential) is closely related to the thought experiment “Einstein’s Boxes”. I presented a new view on this experiment. The main feature of this view is that this experiment is… Read more →

The essential ideaof WISE is given in Ref. [4], together with the linearcombination of unitaries (LCU) formalism of quantumcomputing. LCU has now become one of the major techniquesin quantum algorithm design…. Read more →
The quantum measurement problem is the most fundamental question of all: How the ghostly quantum mechanical coexistence of many mutually incompatible possibilities result in the concrete reality of the normal world, even though we and our measuring instruments are all made of atoms obeying quantum mechanics. In this brief article we lay down the criteria for such a mechanism.
Recently, discussions of fundamental problems of (non-relativistic) quantum mechanics usually concern Bell’s inequalities. As for the discussions around the Schrödinger’s cat paradox, they faded into the background. At the same time, the discussion of Bell’s inequalities suggests that the Schrödinger’s cat paradox has already been resolved. Therefore, it is worth returning to the Schrödinger’s cat paradox to make sure that,… Read more →
