This paper explores the intersection of solid-state physics and geochemistry, proposing a mechanism for the environmental modulation of nuclear decay rates. Moving beyond the concept of decay as a fixed stochastic constant, we analyze how high-symmetry mineral lattices (such as zircons, zeolites, and beryls) can act as natural quantum resonators. Using the framework of the Quantum Zeno Effect (QZE), we demonstrate how the structural symmetry of crystalline cavities, "activated" by the Earth's geomagnetic field (GMF), suppresses nuclear decay pathways. Key highlights: Lattice-Locking: How periodic crystalline potentials restrict the phase space of decay products. Geomagnetic Activation: The role of the Earth's field in maintaining quantum coherence within mineral traps. Geochemical Implications: A new perspective on isotopic anomalies and the potential variability of the geochronological clock during geomagnetic excursions. This research provides a deterministic approach to isotope stability, bridging quantum optics with mineralogical science.

The continuous observation of a quantum system is known to suppress its time evolution, a phenomenon recognized as the Quantum Zeno Effect (QZE). While typically applied to discrete atomic transitions and two-level open quantum systems, extending this principle to nuclear decay processes offers profound implications for controlling nuclear fission. In this paper, we hypothesize a novel containment architecture utilizing closo-borane and nido-borane molecular cages (e.g., B12H122−) as resonant structural cavities. By embedding metastable isotopes within these cages and subjecting the system to continuous, specific electromagnetic excitation, the secondary fluorescence of the cage acts as an unbroken projective measurement. This continuous interaction effectively confines the nuclear state vector to its initial unstable sub-space. Furthermore, we theorize that the simultaneous removal of this monitoring field across a bulk medium of confined isotopes will lead to a highly correlated release from the Zeno-suppressed state. Drawing parallels to Dicke superradiance, this sudden restoration of normal decay channels in a dense, heavily correlated macroscopic ensemble precipitates an avalanche of stimulated nuclear transitions, acting as a triggered synchronization of fission without the traditional critical mass requirements.

While typically applied to discrete atomic transitions, extending this principle to nuclear decay processes offers profound implications for controlling nuclear fission. In this paper, we hypothesize a containment architecture utilizing endohedral buckminsterfullerenes (M@C60) as resonant structural cavities for metastable isotopes. The carbon-12 matrix provides a spin-zero, decoherence-free boundary, severely limiting magnetic interactions. By subjecting the system to continuous electromagnetic excitation, the secondary fluorescence of the cage acts as an unbroken projective measurement, effectively confining the nuclear state vector to its initial unstable sub-space.

Traditional initiation of nuclear fission requires active energy delivery or the achievement of critical mass through physical compression. This paper proposes an inverse paradigm: a "fail-deadly" nuclear trigger activated by the sudden absence of a stabilizing signal. By utilizing the Quantum Zeno Effect (QZE) within resonant molecular cages (endohedral fullerenes and closo-boranes), unstable isotopes can be maintained in a frozen, highly correlated phase state via continuous electromagnetic measurement. The loss of this signal acts as a trigger, leading to immediate Dicke superradiance and a synchronized nuclear avalanche. This paper further analyzes the divergent post-initiation behaviors: while the fullerene matrix (M@C60) functions as a transparent macroscopic emitter of thermalized neutrons, the borane matrix acts as an intrinsic absorber, converting the released nuclear energy into a strict, localized thermal pulse.
Abstract Quantum coherence underpins the performance of all quantum technologies, from error-resistant operations to long-lived quantum memories and ultrasensitive sensors. Despite steady advances, coherence remains fundamentally constrained by environmental noise, most notably, from nuclear spins embedded in the host lattice. Protocol-level strategies, such as dynamical decoupling or operation at clock transitions, mitigate this noise externally but impose control overhead. In contrast, materials-based approaches—especially isotopic purification—directly suppress decoherence at its source. Here, we introduce a unified periodic table of quantum coherence that quantifies coherence limits element by element, incorporating both natural isotope distributions and practical routes for isotopic enrichment. Importantly, this framework provides, for the first time, theoretical upper bounds ( T 2,max ) for all stable elements, offering a quantitative ceiling on what isotopic purification can achieve. The table reveals where purification yields decisive improvements, where alternative strategies must prevail, and where supply or regulatory barriers constrain feasibility. Beyond guiding the search for solid-state qubit hosts, it uncovers overlooked opportunities in functional oxides and related compounds. More broadly, this framework positions isotope engineering as an increasingly important tool for identifying and realizing future quantum-coherent materials. Impact statement Quantum coherence is the essential resource for all quantum technologies, yet it is fundamentally constrained by nuclear spins in the host lattice for solid-state qubits. While active controls can mitigate decoherence externally, materials-based approaches—most notably isotopic purification—suppress noise at its physical origin. In this work, we introduce a unified periodic table of quantum coherence that establishes, for the first time, theoretical upper bounds on spin coherence ( T 2,max ) across the entire set of stable elements. By systematically incorporating both natural isotope distributions and realistic pathways for isotopic enrichment, this framework reveals where purification can yield decisive improvements, where alternative strategies must dominate, and where supply or regulatory barriers impose practical limits. Beyond guiding the search for solid-state spin qubit hosts, the analysis uncovers overlooked opportunities in materials and highlights new design rules for exploiting isotope engineering. More broadly, this periodic table positions isotopic purification as a universal principle for identifying, evaluating, and realizing quantum-coherent materials. The results thus have implications not only for advancing quantum information science, but also for materials synthesis, isotopic supply chains, and the integration of quantum coherence considerations into the broader practice of materials design.

The radioactive decay of metastable isotopes is conventionally understood as an irreducible, random quantum event governed by Fermi's Golden Rule. This paper challenges that paradigm by treating the universe as a 4D barotropic superfluid structured by a B4 tesseractic lattice. In this framework, an unstable atomic nucleus is modeled not as a probability wave, but as a highly frustrated F4 topological defect (a meta-vortex) seeking hydrodynamic relaxation. By physically encapsulating these isotopes within highly symmetric molecular cavities, we demonstrate that the structural geometry of the host molecule imposes rigid boundary conditions on the local vacuum lattice. This paper introduces detailed mathematical models for two specific molecular architectures: Endohedral Fullerenes (M@C60): Utilizing Ih point-group symmetry and a spin-zero carbon matrix to act as neutral geometric pinning centers that freeze the vortex winding number. Polyhedral Boranes (B12H122−): Utilizing intense charge-lattice coupling to locally compress the vacuum, artificially inflating the shear modulus and creating a steep topological impedance barrier. Both mechanisms effectively "pin" the nuclear F4 meta-vortex, artificially halting its decay and stabilizing the isotope indefinitely. Triggered Superradiance (N2 Cascade): Beyond stabilization, this paper provides the exact mathematical derivation for the synchronized release of this topological lock. By applying a resonant pulse to shatter or distort a macroscopic ensemble of N phase-locked molecular cages, the trapped vortices are released simultaneously. Because their rotational phases are perfectly synchronized with the B4 lattice, their individual velocity fields interfere constructively. This precipitates a coherent, anisotropic energy cascade (The TRFC Lighthouse Effect) where the collective relaxation rate scales with N2 (Dicke superradiance). This framework establishes the foundational physics for critical-mass-free nuclear energy architectures, allowing for the on-demand, triggered release of immense binding energy from otherwise stable isomeric materials.
