This work investigates how temporal order and causal structure can emerge from quantum dynamics without assuming a pre-existing background notion of time. Previous studies showed that asymmetric entanglement can generate internally coherent oscillations (”relational ticks”) that serve as a local, operational signature of time for the entangled subsystem. Here we extend this framework to address a fundamental question: can such locally generated ticks propagate to neighbouring systems?Using a minimal asymmetric two-qubit pair as the fundamental temporal element, we demonstrate two key results. The first is that entanglement asymmetry produces a stable internal beat frequency. The second is when these pairs are coupled along a finite quantum chain, the resulting temporal density propagates outward in a clear, finite-speed light-cone structure. Numerical simulations using a Lieb–Robinson style half-maximum criterion reveal a bounded signalling speed v∗, confirming that temporal influence spreads only within a causal cone.Importantly, this finite propagation speed arises directly from local quantum interactions and does not require any relativistic postulates, Lorentz symmetry, or a predefined time coordinate. In the coarse-grained limit, the temporal density exhibits wave-like behaviour with a characteristic speed approaching v∗, suggesting a pathway from microscopic entanglement asymmetry to macroscopic causal order.These results support a concrete mechanistic model in which time emerges from movement, causality emerges from locality, and a finite propagation speed arises naturally from asymmetric entanglement alone. This provides a plausible route by which relativistic causal structure may originate from the dynamics of quantum correlations.

Time is typically treated as a fundamental background parameter or as an emergent property arising from thermodynamic or geometric considerations. In this report we explore a different origin: the generation of time through asymmetric quantum entanglement. A symmetrically entangled pair possesses exchange-indistinguishability; its joint dynamics yield no relational change and therefore no internal temporal reference. However, when symmetry is broken—through a structural or dynamical asymmetry applied to one member of the pair—the correlations between the two subsystems evolve non-identically while remaining entangled. This relational change provides the minimal operational signature of a “tick,” offering a microscopic mechanism for the emergence of time. We construct and analyse a minimal asymmetric entanglement unit comprising an A–B entangled pair and a third system C that couples asymmetrically to A. Numerical simulations of this triplet demonstrate coherent periodic structure in both the trace distance of B relative to its symmetric evolution and in the concurrence of the A–B entanglement scaffold. These oscillations constitute a locally generated temporal reference. We then extend this model to chains of multiple A–B–C units and show that locally generated ticks propagate through neighboring cells, giving rise to a smooth temporal density field along the chain. This illustrates a potential pathway by which microscopic asymmetry-induced ticks may accumulate to form a macroscopic temporal frame. Although exploratory in scope, this work provides one of the most explicit and operational demonstrations to date of how time may arise from purely quantum-mechanical processes. The model highlights asymmetric entanglement as a plausible generator of temporal structure and lays the groundwork for coarse-grained temporal field theories and potential connections to gravitational time dilation.
This paper develops a consistent and self-contained formulation of external (physical) time as an emergent quantity, arising from the internal temporal evolution of correlational sites within the Universal Correlational Lattice (UCL) framework. Rather than assuming time as a fundamental background parameter, the theory distinguishes between: Internal times, defined locally at each correlational site through intrinsic dynamical evolution, and External time, which emerges relationally from the synchronization, ordering, and stability of correlations among multiple sites. The work formalizes how a coherent, observer-independent notion of temporal flow can arise without postulating a pre-existing global clock. External time is shown to correspond to a coarse-grained, effective parameter that captures persistent, ordered correlations across the correlational network, while remaining compatible with regimes where no global time is well-defined. Key results include: A precise definition of temporal evolution along internal time without reference to external time units. The emergence of a one-parameter effective temporal ordering from correlational dynamics. A clear separation between pre-geometric (timeless or multi-temporal) regimes and geometric regimes where an effective spacetime description becomes valid. Conceptual and mathematical consistency with relativistic causality, decoherence, and macroscopic temporal stability. This framework provides a natural resolution to longstanding tensions between quantum theory and general relativity regarding the status of time, without invoking collapse postulates or external observers. Time is not fundamental, but real and physical as an emergent, relational structure. The paper is intended for researchers interested in foundational questions of time, quantum gravity, emergent spacetime, and relational approaches to physics.
A universal speed limit is derived using only Postulates P1 and P2 of the Quantum Entanglement Spacetime Theory (QuEST). No assumptions regarding metric geometry, field equations, or physical constants are introduced. The result follows solely from symbolic execution of local state influence over a discrete quantum hypergraph. The emergent maximum signal speed arises from finite causal connectivity and strict locality, and aligns with the observed speed of light under continuum coarse-graining. This derivation establishes the structural sufficiency of P1 and P2, independent of geometric constructs or continuum assumptions.
This preprint clarifies a persistent category error in the interpretation of quantum mechanics and relativity by explicitly distinguishing propagation from correlation. Relativistic constraints, including the finite speed of light, apply to the transmission of energy, matter, and information through spacetime. Quantum mechanics, by contrast, permits nonlocal correlations between entangled systems that do not involve transmission, motion, or signal propagation. The apparent instantaneity of quantum effects therefore reflects the revelation of pre-existing correlation structure rather than superluminal dynamics. By maintaining this separation, the preprint shows that the finite speed of light and quantum nonlocality are not in conflict. Light is limited in speed because it propagates; quantum correlations have no speed because nothing propagates. This framing resolves common misconceptions surrounding entanglement, nonlocality, and causality without introducing hidden structures, preferred frames, or violations of relativistic invariance. The work is intended as a conceptual clarification and falsifiable interpretive framework, not a modification of quantum theory or relativity.

We give a causal inference scheme using quantum observations alone for a case with both temporal and spatial correlations: a bipartite quantum system with measurements at two times. The protocol determines compatibility with five causal structures distinguished by the direction of causal influence and whether there are initial correlations. We derive and exploit a closed-form expression for the spacetime pseudo-density matrix (PDM) for many times and qubits. This PDM can be determined by light-touch coarse-grained measurements alone. We prove that if there is no signalling between two subsystems, the reduced state of the PDM cannot have negativity, regardless of initial spatial correlations. In addition, the protocol exploits the time asymmetry of the PDM to determine the temporal order. The protocol succeeds for a state with coherence undergoing a fully decohering channel. Thus coherence in the channel is not necessary for the quantum advantage of causal inference from observations alone.
This paper addresses a foundational question in the Universal Correlational Lattice (UCL) framework: under what precise conditions does an effective notion of time emerge? Unlike standard formulations in quantum mechanics or relativity, the UCL framework does not assume time as a primitive background parameter. Instead, temporal structure arises from the correlational dynamics encoded in the universal kernel and the internal evolution of correlational sites. While this opens the possibility of a relational and emergent notion of time, it also raises a critical issue: not all correlational configurations lead to a physically meaningful temporal ordering. This work introduces explicit admissibility conditions that determine when emergent time is well-defined, stable, and physically interpretable. These conditions restrict the space of allowed correlational solutions and act as a selection principle separating dynamically viable temporal structures from purely formal or pathological ones. Key aspects developed in the paper include: Criteria for synchronization of internal evolutions and the construction of an effective external time parameter. Conditions ensuring monotonicity, ordering, and causal consistency of emergent temporal flows. The role of modular evolution and one-parameter internal groups in establishing temporal coherence. Stability requirements under functional variation, coarse-graining, and decoherence limits. Clarification of when emergent time can be treated as observer-independent and when it remains context-dependent. By making these constraints explicit, the paper closes an important conceptual gap in emergent-time approaches. It provides a rigorous foundation for the use of time-dependent dynamics within the UCL framework and delineates the domain of validity of emergent temporal descriptions across different physical regimes. This work is intended as a foundational contribution, complementing previous developments of the UCL framework and enabling consistent application of emergent time in subsequent dynamical, phenomenological, and comparative studies.
