一段有限的量子过程能否生成相同制备态绝不会确定性达到的经典未来？我们以暴胀为宇宙学实验室证明其可行。在我们的超引力实现中，已存在两条经典延续路径，但制备态在无噪声时仅能到达其中一条；一个稳定熵方向会在无快子不稳定性的情况下暂时变轻，使模式导出的相空间涨落能进入竞争的另一条延续路径。有限视界首通时间为三条邻近CMB归一化实现分配了0.33至0.40的条件权重，而抑制随机源则会恢复其精确的确定性零值；随后熵 sector 再次变重，所选历史继续经典演化。因此，一段有限的量子过程可在经典未来间留下持久的重新分布。
英文摘要
Can a finite quantum episode populate a classical future that the same prepared state never reaches deterministically? We show that it can, using inflation as a cosmological laboratory. In our supergravity realization, two classical continuations already exist, but the prepared state reaches only one without noise. A stable entropy direction temporarily becomes light without a tachyonic instability, allowing mode-derived phase-space fluctuations to access the competing continuation. Finite-horizon first passage assigns it a \(0.33\)--\(0.40\) conditional weight across three nearby CMB-normalized realizations, while suppressing the stochastic source restores its exact deterministic zero. The entropy sector then becomes heavy again, and the selected histories continue classically. A finite quantum episode can thus leave a lasting redistribution among classical futures.
