论文摘要
量子力学通常是通过隐式假设制定的，即可以观察和与世界相互作用的代理在其外部并具有经典记忆。但是，没有可接受的方法来定义量子古典剪切，也没有先验理由来排除具有连贯的量子记忆的完全量子剂。在这项工作中，我们引入了一个完全量子的测量概念，称为感觉，以说明通过量子传感器体验世界的量子剂。感觉避免了概率，而是描述了量子信息的确定性流动。我们使用量子信息理论的概念量化了感官的信息获得和干扰，并发现感觉始终与他们所告知的概念始终干扰。将测量值视为感觉可能会导致对量子理论的新理解，并在量子网络的背景下产生新的结果。
Quantum mechanics is usually formulated with an implicit assumption that agents who can observe and interact with the world are external to it and have a classical memory. However, there is no accepted way to define the quantum-classical cut and no a priori reason to rule out fully quantum agents with coherent quantum memories. In this work, we introduce an entirely quantum notion of measurement, called a sensation, to account for quantum agents that experience the world through quantum sensors. Sensations eschew probabilities and instead describe a deterministic flow of quantum information. We quantify the information gain and disturbance of a sensation using concepts from quantum information theory and find that sensations always disturb at least as much as they inform. Viewing measurements as sensations could lead to a new understanding of quantum theory in general and to new results in the context of quantum networks.
