Abstract Quantum entanglement and quantum nonlocality are examined in the context of the fundamental relationship between spacetime symmetry and conservation laws. It is established that quantum nonlocality arises from the very structure of spacetime. Arguments are presented in favor of the secondary nature of the spacetime continuum relative to more fundamental principles and concepts of the microworld. An example is given of a closed quantum entangled system, which demonstrates that such a system behaves as an indivisible whole: its particles are inseparably linked through the conservation of momentum. Physically, this manifests as strict correlations in measurements—correlations that must be nonlocal in nature. This supports the idea that there exist deep mechanisms of coordination, such as the principle of reciprocity between coordinate and momentum representations, and binary relations permeating the fabric of nonlocal spacetime. To understand the coherent behavior of such systems, it is necessary to move beyond local reductionism and accept the objective reality of global connections that bind the elements of the system into a unified ensemble.

Entanglement and Nonlocal Coherence: Why Nonlocality Is Natural in a Phase Ontology (Phase Ontology — Part IV) reframes quantum entanglement by changing the usual starting assumption. The paper argues that entanglement only looks paradoxical if spacetime separation is assumed to imply ontological separation. If phase coherence is treated as a primary layer of reality (as developed in Parts I–III), then nonlocal correlations become expected rather than mysterious. In this view, entangled systems share a single coherent phase structure prior to measurement. Measurement is described as local phase locking: an interaction with a detector stabilizes a definite outcome locally, while the joint correlations arise because both outcomes are constrained by the same underlying phase structure. No superluminal signal is required; correlations are revealed rather than transmitted. The paper also addresses compatibility with relativity: since no information is communicated faster than light, relativistic causality remains intact. Locality is treated as an emergent property of spacetime, while coherence relations can be nonlocal because they are not fundamentally “in spacetime” to begin with. This manuscript is Part IV of a seven-part series (Parts I–VII). It connects the measurement framework of Part III to entanglement and points ahead to Part V (time, irreversibility) and Part VII (experimental implications and falsifiability).
Quantum entanglement, a quintessential feature of quantum mechanics, has profound implications on our understanding of the fundamental nature of reality. This phenomenon, in which quantum particles exhibit correlations that defy classical intuition, has captivated physicists and philosophers alike. The existence of nonlocal correlations, a hallmark of entanglement, challenges the principles of local realism and calls into question our notions of causality and locality. This paper explores the theoretical foundations, experimental evidence, and interpretations surrounding quantum entanglement and nonlocal correlations. It delves into the historical context, highlighting the pioneering work of physicists such as Einstein, Podolsky, Rosen, and Bell, whose contributions paved the way for our current understanding of this enigmatic concept. The paper also examines the potential applications of entanglement in fields such as quantum computing, cryptography, and communication, underscoring its technological significance. Furthermore, it discusses the philosophical implications of nonlocal correlations, shedding light on the ongoing debates surrounding the interpretation of quantum mechanics and the nature of reality itself. Keywords: Quantum entanglement, Nonlocal correlations, Local realism, Causality, Locality, Quantum mechanics, Experimental evidence, Theoretical foundations, Einstein-Podolsky-Rosen (EPR) paradox, Bell's theorem, Quantum computing.
Quantum entanglement and nonlocality are two of the most profound and puzzling concepts in modern quantum mechanics. Quantum entanglement refers to the phenomenon where particlesbecome correlated in such a way that the state of one particle instantly influences the state ofanother, even if they are separated by vast distances. Nonlocality, a concept closely related toentanglement, challenges our classical understanding of locality and causality, suggesting thatparticles can communicate instantaneously, defying the limitations imposed by the speed oflight. This paper explores the theoretical foundations of entanglement and nonlocality, theirexperimental validations, and their implications for future technologies, particularly in quantum computing and quantum communication. Furthermore, the study delves into thephilosophical ramifications of these phenomena, discussing their impact on our understandingof the nature of reality and the fundamental laws of physics
Although entanglement is widely recognized as one of the most fascinating characteristics of quantum mechanics, nonlocality remains to be a big labyrinth. The proof of existence of nonlocality is as yet not much convincing because of its strong reliance on Bell's theorem where the assumption of realism weakens the proof. We demonstrate that entanglement and quantum nonlocality are two equivalent aspects of the same quantum wholeness for spacelike separated quantum systems. This result implies that quantum mechanics is indeed a nonlocal theory and lays foundation of understanding quantum nonlocality beyond Bell's theorem.
The nonlocality of entangled quantum mechanical systems is incompatible with the standard interpretation of special relativity as a single 4D Minkowskian metric spacetime. The difficulty is that the definition of a spacetime interval between any pair of events precludes any form of nonlocal interaction, even the relatively benign non-signaling correlations. By an application of the relativity principle, and the use of the space ←→ time symmetry of the Lorentz boost I propose here a reinterpretation of special relativistic spacetime. This new ontology consists of a set of coexisting 3+1D spaces (‘framespaces’), each containing unique content in the form of a complex density. These spaces are related by the Lorentz boost, and coupled pairwise in a manner dictated by the Lorentz transformation. The inter-space coupling acting on the spacetime content gives rise to a nonlocal wave phenomenon, which is identified as quantum wave mechanics. The interspace coupling strength is then inversely proportional to Planck’s constant. The coexistence of multiple spaces is interpreted as momentum superposition, implying that momentum is the fundamental physical basis of quantum superposition. This new spacetime interpretation of quantum mechanics has many consequences, including explanations of quantum non-locality, the spacetime role of Planck’s constant, quantum measurement as a symmetry-breaking process and the redundancy of description of gauge theory.
One of the fundamental questions in physics concerns the relation between spacetime and quantum entanglement. The spacetime is usually considered as a fixed background physical space, and the quantum entanglement is usually manifested as a ``spooky action at a distance" or the existence of ``nonlocality" in nature. Here, we propose the flat-space isotropy and homogeneity principles as the fundamental criteria for determining the maximum degree of nonlocality of nature. More specifically, we consider abstract and deterministic nonlocal-box models which have stronger correlations than in quantum mechanics, whereas therein instantaneous communication remains impossible. We impose space-symmetry group structures on these models and derive a measure for the degree of space symmetries. Surprisingly, there is a tradeoff or inconsistency between the degree of space symmetries and the degree of nonlocality, where this inconsistency is exactly lifted at the Tsirelson bound, as predicted by quantum physics and also predicted in the experiments. Moreover, we prove this result in the general framework of deterministic nonlocal models and conclude that the probabilistic interpretation of the nonlocal box models is an emergent property of the flat-space symmetries.
