Abstract

A quantum entangled state is a quantum superposition state. The principle of quantum superposition, and therefore the existence of quantum entanglement, is contingent upon the validity of quantum theory. Thus, the generation of quantum entanglement requires that interactions occur between small-mass particles localized in a confined spatial region, resulting in each particle’s quantum state being a bound state. In other words, the prerequisite for the validity of quantum theory must be satisfied. At the same time, conserved quantities must exist between quantum superposition states, as only quantum states with conserved quantities can undergo superposition, allowing the particle system to generate quantum entangled states. Quantum entangled states can occur between electrons within an atom, between atoms, between molecules, or between atoms and molecules. Within the atomic nucleus, quantum entanglement can exist among protons, neutrons, and the quarks. In superconductivity, superfluidity, and Bose-Einstein condensation, they manifest as macroscopic quantum entanglement, which respectively come from the statistical results of a large amount of microscopic quantum entanglement between electrons, atoms or molecules. For massive macroscopic objects, they exhibit classical properties that cannot be described by quantum theory, and the principle of quantum superposition does not hold. Therefore, no entangled state is generated. It should be particularly emphasized that even for microscopic particle systems, if they exist in a large spatial region, they cannot be described by quantum theory. In such cases, the quantum superposition principle does not hold, and quantum entanglement phenomena do not exist. Therefore, within a large spatial region, multi-electron, multi-photon, and other microscopic systems do not have quantum entangled states; under certain conditions, quantum correlated states can be generated. Consequently, in a large spatial region, the mainstream viewpoints about non-locality—such as the so-called instantaneous collapse of entangled particles during measurement, infinite propagation speed, and the “spooky action at a distance”—are all incorrect. In experiments related to quantum communication and the verification of Bell’s inequality, the quantum states used are quantum correlated states rather than quantum entangled states. Regardless of whether the systems are microscopic or macroscopic, phenomena occurring in a large spatial region must adhere to the principles of causality, realism, and locality. In other words, Einstein’s viewpoint is correct.

Violation of Bell's Inequality

George Rajna

Quantum entanglement, one of the most intriguing features of multi-particle quantum systems, has become a fundamental building block in both quantum information processing and quantum computation. [10] The microscopic world is governed by the rules of quantum mechanics, where the properties of a particle can be completely undetermined and yet strongly correlated with those of other particles. Physicists from the University of Basel have observed these so-called Bell correlations for the first time between hundreds of atoms. [9] For the past 100 years, physicists have been studying the weird features of quantum physics, and now they're trying to put these features to good use. One prominent example is that quantum superposition (also known as quantum coherence)—which is the property that allows an object to be in two states at the same time—has been identified as a useful resource for quantum communication technologies. [8] Quantum entanglement—which occurs when two or more particles are correlated in such a way that they can influence each other even across large distances—is not an all-or-nothing phenomenon, but occurs in various degrees. The more a quantum state is entangled with its partner, the better the states will perform in quantum information applications. Unfortunately, quantifying entanglement is a difficult process involving complex optimization problems that give even physicists headaches. [7] A trio of physicists in Europe has come up with an idea that they believe would allow a person to actually witness entanglement. Valentina Caprara Vivoli, with the University of Geneva, Pavel Sekatski, with the University of Innsbruck and Nicolas Sangouard, with the University of Basel, have together written a paper describing a scenario where a human subject would be able to witness an instance of entanglement—they have uploaded it to the arXiv server for review by others. [6] The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron’s spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the relativistic quantum theory.

The quantum mystery: reality, knowledge, and the limits of science

Ecaterina Lozovanu

For over nine decades, quantum mechanics has profoundly shaped our understanding of nature, offering explanations for the stability of atoms, the formation of mole cules, the properties of materials, and phenomena such as light or radioactivity. It is essential to modern technologies—from microchips to lasers—and underpins the physics of elementary particles. Yet, despite its successes, it remains a deeply mysterious theory, confronting a central enigma: why does the quantum world behave so differently from everyday reality? Elements such as superposition and quantum entanglement—which allow particles to exist simultaneously in multiple states or remain interconnected regardless of distance—contradict classical world intuitions. This gap between microscopic and macroscopic behavior has given rise to what is known as the “measurement problem,” raising fundamental questions about the nature of reality. Diverging interpretations have led to two major schools of thought: anti-realism, promoted by Niels Bohr, which holds that reality depends on the observer and their interaction with measurement instruments; and realism, supported by Albert Einstein, which argues that quantum mechanics is incomplete and that eality exists independently of observation. Bohr’s complementary philosophy and Heisenberg’s uncertainty principle were central to the formulation of the “Copenhagen interpretation,” which became dominant in the 20th century. However, the persistent opposition of scientists like Einstein and Schrödinger inspired generations of physicists to seek a unification between quantum mechanics and relativity, culminating in new theories such as loop quantum gravity and string theory. Thus, the debate between realism and anti-realism remains alive, and philosophy continues to play a crucial role in exploring the new foundations of physics.

On Quantum Superposition

Guang-Liang Li

Lying at the heart of quantum mechanics, the notion of quantum superposition causes enormous difficulty in understanding the problem of quantum measurement, which concerns the Einstein-Bohr debate on the conceptual foundations of the quantum theory. According to Bell’s theorem, Einstein’s viewpoint in his debate with Bohr seems to be wrong. In the present paper, a new principle (referred to as the general principle of measurements) is introduced and proved as a mathematical theorem. Based on this principle, various forms of quantum superposition (including quantum entanglement) and the corresponding experiments are scrutinized. The main findings are as follows. (a) Einstein’s viewpoint is correct and Bell’s theorem is problematic. (b) Measurement outcomes of any actual experiment with individual microscopic objects described in a form of quantum superposition, in particular, the experimental results of testing Bell inequalities, are all erroneously explained. (c) Bell inequalities failed to capture the essence of the Einstein-Bohr debate, i.e., whether quantum superposition is legitimate for describing individual microscopic objects. (d) All kinds of quantum superposition violate the general principle of measurements and hence are illegitimate. (e) Quantum mechanics can be completed by using disjunction (“or”) as the logical relation between the orthonormal vectors that span an arbitrarily given Hilbert space for describing a single microscopic object, and the mathematical setting will remain essentially unchanged; hidden-variable theories are irrelevant to the real world. (f) After completing quantum mechanics as above, the difficulty in understanding the problem of quantum measurement disappears naturally. Implications of the findings are also discussed.

Entanglement and Non‐Locality: Spooky Actions at a Distance

Christopher C. Gerry, Kimberley M. Bruno

This chapter focuses the concepts of entanglement and non-locality. Quantum mechanics has yet another mystery—one that occurs as a consequence of superposition states involving two or more particles or two or more beams of photons. This is referred to as entanglement, also known as non-separability. The existence of entangled states is allowed, and even mandated, by quantum mechanics, and this leads us into yet another mystery: non-locality. It demonstrates how subatomic particles can be put into entangled states which reveal strange correlation effects—the effects being the essence of entanglement. It discusses the EPR argument, from the 1935 paper by Einstein, Boris Podolsky, and Nathan Rosen; the polarization states of photons; Bell's theorem; and the Hardy–Jordan argument.

Introduction

Alisa Bokulich, Gregg S. Jaeger

Entanglement can be understood as an extraordinary degree of correlation between states of quantum systems – a correlation that cannot be given an explanation in terms of something like a common cause. Entanglement can occur between two or more quantum systems, and the most interesting case is when these correlations occur between systems that are space-like separated, meaning that changes made to one system are immediately correlated with changes in a distant system even though there is no time for a signal to travel between them. In this case one says that quantum entanglement leads to non-local correlations, or non-locality. More precisely, entanglement can be defined in the following way. Consider two particles, A and B, whose (pure) states can be represented by the state vectors ψA and ψB. Instead of representing the state of each particle individually, one can represent the composite two-particle system by another wavefunction, Ψ AB. If the two particles are unentangled , then the composite state is just the tensor product of the states of the components: Ψ AB = ψ A ⊗ ψ B; the state is then said to be factorable (or separable). If the particles are entangled, however, then the state of the composite system cannot be written as such a product of a definite state for A and a definite state for B. This is how an entangled state is defined for pure states: a state is entangled if and only if it cannot be factored: Ψ AB ≠ ψ A ⊗ ψ B.

On the Instantaneous Gravitational Binding of the Zero-Mass Wave State by the Inverted Singularity (Four-Dimensional Cosmic Membrane): A General Relativistic Interpretation of Quantum Superposition and Entanglement

SYU JIA WUN

This research aims to thoroughly resolve the century-long core conflict in fundamental assumptions and ontology between General Relativity (GR) and Quantum Mechanics (QM) in modern physics. We strictly challenge and overturn the mainstream phenomenological viewpoint of the Copenhagen Interpretation regarding the "Ontological Indeterminacy" of the microscopic world. Grounded in the grand framework of the Grand Unified Theory of Cosmic Mind (GUTCM), we propose an absolute geometric determinism model based on "Massless Dynamics" and "Inverted Singularity Topology (i.e., the Four-Dimensional Spatial Cosmic Membrane)." Through extreme dynamical argumentation, this paper points out that the superposition and randomness exhibited in quantum phenomena are by no means mysterious attributes built into microscopic entities. Their physical essence is the inevitable "Spacetime Aliasing" effect produced by macroscopic observers—limited by the low gravitational field spacetime metric and sluggish observational resolution—when perceiving extremely high-frequency physical interaction processes. To precisely describe this underlying operation, we integrate the 0/∞ Nothingness Model Reconstruction to establish two core mechanisms: The Infinite-Speed Processor Essence of the Four-Dimensional Inverted Singularity: The traditional Big Bang singularity is dead, but the inverted singularity of this universe is essentially a "four-dimensional spatial cosmic membrane" relentlessly crushed into existence by the absolute vacuum acting upon saturated particles. This physical membrane is constantly undergoing inside-out inversion at infinite speed, enveloping us (three-dimensional spacetime) within it. Therefore, the inverted singularity does not linger in the past, but is the "eternal present," possessing infinite topological tension and computational speed. Proper Time Collapse and Instantaneous Geometric Ergodicity: According to General Relativity, when a wave-state entity with rest mass m=0 moves along a null geodesic, its subjective proper time dτ≡0. When the zero-mass wave state contacts the ubiquitous four-dimensional cosmic membrane (inverted singularity), it essentially enters a server with "infinite computational speed." This endows the wave state with the absolute physical ability to achieve "instantaneous ergodicity" over the three-dimensional global spacetime coordinates without violating macroscopic causality. Based on this rigorous geometric framework, this research redefines and deconstructs two major quantum paradoxes of contemporary physics: Quantum Superposition: This is actually the trajectory afterimage left by the particle undergoing extreme high-frequency oscillation between the "infinite-speed processing layer of the four-dimensional inverted singularity (cosmic server-side)" and the "three-dimensional macroscopic spatial coordinates (observation client-side)." The wavefunction ∣Ψ∣² in the Schrödinger equation does not describe an ethereal probability of existence, but rather the "time-averaged distribution density" of the particle on this high-frequency cyclic path. Quantum Entanglement: All microscopic wormholes (ER bridges) are not randomly connected in three-dimensional space, but are directly connected to the "four-dimensional cosmic membrane (inverted singularity)" enveloping three-dimensional spacetime. Entangled particles, within the topological structure of the 4D membrane, strictly share a single "fully connected vertex." The so-called non-local spooky action is in fact the multiple geometric projections of a single high-dimensional information entity onto a three-dimensional manifold, possessing an indisputable "topological identity" at its core. This theory successfully blows away the non-deterministic fog of quantum mechanics entirely, perfectly converging it within the rigid geometric framework of General Relativity. We prove that the action at a distance and superposition in quantum mechanics are purely the mechanized, instantaneous mechanical reactions inevitably exhibited by the zero-mass wave state upon contacting the ubiquitous four-dimensional inverted singularity that possesses infinite-speed inversion capability.
