Decoherence Truncation in Quantum Interference: A Binary Locking Model vs. Exponential Decay in Fullerene Experiments

Abstract

Abstract Conventional decoherence theory predicts that the visibility of quantum interference decays exponentially as the interaction with an environmental probe increases. In this brief report, we propose an alternative phenomenological model based on a "binary locking" mechanism, where the transition from a quantum superposition to a definite state is a topological event rather than a continuous process. We compare the standard exponential decay model with our linear locking model, V=1−αPV=1−αP, against the experimental data from laser-grating interference of C60 and C70 fullerenes (arXiv:0902.0234). While both models fit the low-power regime, the exponential model fails to explain the sharp truncation (abrupt drop to zero) of interference visibility observed in C70 at high probe powers (around 16-17 W). The Pure Locking Inference (PLI) binary locking model naturally predicts this critical truncation, providing a novel perspective on the quantum-to-classical transition. 摘要 传统的退相干理论预测,随着与环境探针相互作用的增加,量子干涉的可见度呈指数衰减。在这份简报中,我们提出了一种基于“二元锁定(Binary Locking)”机制的替代唯象模型,该模型认为从量子叠加态到确定态的转变是一个拓扑事件,而非连续过程。我们将标准的指数衰减模型与我们的线性锁定模型(V=1−αPV=1−αP)进行了比较,并对照了 C60 和 C70 富勒烯激光光栅干涉实验的数据(arXiv:0902.0234)。虽然两种模型在低功率区域都能拟合数据,但指数模型无法解释在 C70 高探针功率(约 16-17 W)下观测到的干涉可见度的突然截断(断崖式降至零)。纯锁定推理(Pure Locking Inference, PLI)的二元锁定模型自然地预测了这种临界截断,为量子到经典的过渡提供了一个全新的视角。
