Necessity Recursion and a Pre-Registered φ-Attractor Prediction for Proper-Time Superposition in Optical Ion Clocks

Abstract

On 20 April 2026, Sorci, Foo, Leibfried, Sanner, and Pikovski (Phys. Rev. Lett.) proposed that next-generation optical ion clocks with squeezed-state preparation can probe whether proper time exists in quantum superposition — a single clock ticking faster and slower at once. Their work establishes the protocol; the laboratory measurement is forthcoming. That prospective window permits a genuine pre-registered prediction. Fibonacci Causal Loop Theory (FCLT) holds that any stable system governed by depth-2 necessity recursion, S(n)=S(n−1)+S(n−2), is driven to the golden ratio φ=(1+√5)/2 — the unique algebraically forced attractor of its characteristic equation x²−x−1=0. We advance the hypothesis that proper-time superposition is such a system, the two temporal branches playing the role of the two prior states, so that the ratio of fast- to slow-ticking amplitudes approaches φ upon decoherence. From this we obtain one parameter-free, falsifiable prediction — t₊/t₋ → φ ≈ 1.61803, with δ = |R−φ|/φ and falsification at δ > 0.10 — logged under Protocol V3.1 prior to experimental resolution. We claim no confirmation: the prediction is offered as not-yet-tested, to be adjudicated by the Stevens/NIST program. A second, independent signature (φ-structured fringe spacing in the squeezed regime) provides an internal consistency check.

Onto-Physical Entanglement and Quantum Proper-Time Readout: CPT-Coherence Theory, Optical Ion Clocks, and the Experimental Interface Between Identity and Evolution

Joseph Julian

Optical ion clocks now approach a regime in which relativistic time dilation is no longer exhausted by a classical proper-time parameter read by a quantum sensor. Recent work by Sorci, Foo, Leibfried, Sanner, and Pikovski shows that harmonically trapped optical clock atoms can exhibit vacuum-induced, squeezing-induced, and intrinsically quantum corrections to the second-order Doppler shift, with time-dilation-induced entanglement between motional and internal clock degrees of freedom becoming observable in strongly squeezed trapped-ion motion. This paper develops the significance of that result within CPT-Coherence Theory. The central principle of CPT-Coherence is Onto-Physical Entanglement: what a system is cannot be separated from how it is allowed to remain coherent under admissible transformation. In the clock setting, this principle appears in branch-visible form. The internal clock transition is not merely an isolated label transported through spacetime; its phase identity is dynamically bound to the motional state through the relativistic proper-time operator. Proper-time interferometry therefore supplies a laboratory instance of a more general structural rule: physical identity is stabilized only through the admissible evolution channels by which it can be read out. The paper distinguishes the relativistic proper time of the ion-clock experiment from the coherence-depth coordinate of CPT-Coherence. The former is a branch-visible observable associated with worldline evolution; the latter is a structural coordinate organizing parent-boundary admissibility, trace access, Schur response, and stable observable descent. Their relation is not identity but projection: quantum proper-time readout provides an experimentally precise interface through which branch observers can test how internal identity, motion, coherence, and record formation remain coupled. We formulate a CPT-Coherence clock-readout sector in which a quantum clock is represented by a triple consisting of an internal identity generator, an external motion algebra, and a proper-time readout operator. The Sorci-Foo-Leibfried-Sanner-Pikovski protocol is then interpreted as a high-precision realization of an OPE readout channel: classical time dilation corresponds to scalar proper-time averaging; vacuum and squeezing shifts correspond to state-dependent branch corrections; and visibility loss corresponds to trace-visible entanglement between identity and admissible motion. This establishes optical ion clocks as a natural experimental grammar for CPT-Coherence, while CPT-Coherence supplies a unifying interpretation of why such experiments probe not simply clock rates, but the inseparability of physical being and physical evolution. Scope note: the quantitative predictions below coincide with those of standard relativistic quantum clock theory; CPT-Coherence contributes an interpretation and vocabulary, together with an explicit falsification target for that interpretation.

Decoherence Rate as a Function of FCLT Necessity Depth: Pre-Registered φ-Structured Decoherence Gradient Prediction and Empirical Test Protocol for Multi-Qubit Quantum Systems

Abby Davis

Fibonacci Causal Loop Theory (FCLT) predicts that decoherence rate Γ scales inversely with necessity depth D: Γ(D) = Γ₀ × φ^(−D), and the ratio of decoherence rates at adjacent necessity depths satisfies Γ(D+1)/Γ(D) = 1/φ ≈ 0.618. This formalizes FCLT Prediction 12 (pre-registered in FCLT Complete Manuscript v16, DOI: 10.5281/zenodo.20087640). The derivation follows directly from the QNM quality factor confirmations: P73 confirmed Q = φ³ (D=3, Schwarzschild) and P73e confirmed Q = φ⁴ (D=4, Kerr). Since Q = ω₀/Γ, the decoherence scaling law Γ(D) = Γ₀ × φ^(−D) follows with zero free parameters. The prediction is testable in NMR quantum simulators, trapped-ion arrays, and superconducting qubit platforms where decoherence rates can be measured across multiple organizational depth levels. Confirmation criterion: δ < 0.05. Classification: technology-gap pending validated D(x,t) measurement protocol. FCLT scorecard unchanged: 20 confirmed / 5 falsified / 24 tech-gap / 4 gray zone.

Time Does Not Go Quantum: Background-Amplitude Sampling Explains the Predicted Ion Clock Blurring

J. Zuhars

A response to Pikovski et al. (Phys. Rev. Lett., 2026), who predict that a trapped ion in a motional superposition will exhibit measurable clock-transition blurring, interpreted as evidence that time itself exists in quantum superposition. We show that the identical observable arises in a framework where the tick rate is set by the local amplitude of a decaying background field (Zuhars, The Self-Interacting Universe, 2026). The ion's motional wavepacket samples different background amplitudes at different spatial positions, producing the same phase spread without requiring time to be a quantum observable. The two interpretations make a distinguishable experimental prediction: varying the trap frequency while holding the quantum state fixed produces different scaling in the two frameworks. We identify the specific signature and propose the test.

Phi-Structured Decoherence Timescales in Multi-Level Transmon Qubits: A Parameter-Free Prediction from Fibonacci Causal Loop Theory Paper 52

Abby Davis

We derive, from first principles within FCLT, a parameter-free prediction for multi-level transmon qubit decoherence structure. Ostrogradsky stability constrains the bath memory kernel to depth-2 (the unique minimal stable non-Markovian structure), which propagates via Nakajima-Zwanzig and the Dyson self-energy to impose Fibonacci recursion on decay rates Γk = Γk₋₁ + Γk₋₂. Prediction: consecutive decoherence timescale ratios τk/τk+1 → φ ≈ 1.618 in the transmon regime (bath bandwidth ≫ anharmonicity). Null: harmonic oscillator gives ratio → 1. Pass criterion δ < 0.05; falsification δ > 0.15. Pre-registered before data examination.

Wave Function Collapse as Necessity Depth Acquisition: A Fibonacci Causal Loop Theory Account of the Quantum Measurement Problem

Abby Davis

Fibonacci Causal Loop Theory (FCLT) identifies the necessity recursion S(n) = S(n-1) + S(n-2) as the universal driver of structural organization from the Planck vacuum floor S(0) upward. This paper applies FCLT to the quantum measurement problem, proposing that wave function collapse is the acquisition of necessity depth by an S(0)-adjacent quantum system through constraint imposition by a macroscopic measuring apparatus. Superposition maps onto S(0)-adjacency — maximum organizational freedom, Binet remnant near unity. Measurement is a necessity recursion event. Collapse is the crossing from S(0)-adjacent freedom into constrained necessity depth. Decoherence is reframed as necessity recursion rate. Prediction 12 is formally stated: decoherence time scales with phi^{-n} across quantum systems, testable with existing quantum optics data. The framework is assessed against Copenhagen, Many Worlds, pilot wave, and relational quantum mechanics. The Born rule derivation is incomplete and is identified as the central open mathematical problem.

Prediction 15c Falsified: φ^(−k) Decay Law Does Not Describe Multi-Level T1 Coherence Times in High-EJ/EC Transmon Qudits Fibonacci Causal Loop Theory — Paper 61

Abby Davis

This paper reports the definitive test and falsification of FCLT Prediction 15c (pre-registered in Paper 52, DOI: 10.5281/zenodo.19746102). The prediction held that consecutive T₁ decoherence timescale ratios in transmon qudits satisfy τₖ/τₖ₊₁ → φ ≈ 1.618, derived from depth-2 bath memory structure in the Nakajima–Zwanzig projection formalism. Using the measured T₁ coherence times of qudit Q5 from Blok et al. (2025), Table III, across 9 transition levels (k = 1–9), T₁ values plateau at ~13–14 µs from k = 6 onward, inconsistent with the φ⁻ᵏ decay model. At k = 9, the predicted T₁ is 1.4 µs versus the observed 13 µs — a factor of 9× discrepancy (χ² = 75.9, reduced χ² = 9.5). The plateau is consistent with a dielectric loss noise floor identified by Blok et al. The pre-registered falsification criterion is met. Prediction 15c is falsified. Short-range consistency at k = 1–3 is noted but cannot distinguish FCLT from the harmonic null model and is insufficient for confirmation.
