Quantum decoherence is crucial to understanding the emergence of the classical world from the underlying quantum reality. Decoherence dynamics are unitary, although they superselect a preferred eigenbasis. Decoherence dynamics result in stable macroscopic, localized, classical-like states. We show that the above-mentioned facts imply the possibility of the existence of decoherence-like dynamics that result in stable macroscopic non-localized non-classical-like states. Being rooted in the fabric of the decoherence theory itself, this property implies environments that steer the decoherence towards, for example, spatial superpositions of macroscopic objects. To demonstrate this, we provide thought-experimental, mathematical and philosophical arguments.
量子退相干对于理解从潜在的量子现实中如何出现经典世界至关重要。退相干动力学是幺正的，尽管它们超选了一个优先本征基。退相干动力学导致稳定的宏观、局域化、类经典状态。我们表明，上述事实意味着存在类似退相干的动力学的可能性，这种动力学导致稳定的宏观非局域化非类经典状态。这种特性植根于退相干理论本身的结构中，意味着存在这样的环境，例如，它们能引导退相干朝着宏观物体的空间叠加方向发展。为了证明这一点，我们提供了思想实验、数学和哲学论证。
