论文摘要
量子非马克维亚性和量子达尔文主义是两个与共同主题相关的现象：量子系统和与之相互作用的量子环境之间的量子信息通量。在这项工作中，利用Sudarshan和他的学校发起的Quantum Collision模型，我们将分析有关量子谐波振荡器获得的有关单个Qubit的信息（作为仪表）的效率。我们将展示这种量子信息通量如何效率低下，导致非马尔可夫和非达尔文行为的同时出现
Quantum non Markovianity and quantum Darwinism are two phenomena linked by a common theme: the flux of quantum information between a quantum system and the quantum environment it interacts with. In this work, making use of a quantum collision model, a formalism initiated by Sudarshan and his school, we will analyse the efficiency with which the information about a single qubit gained by a quantum harmonic oscillator, acting as a meter, is transferred to a bosonic environment. We will show how, in some regimes, such quantum information flux is inefficient, leading to the simultaneous emergence of non Markovian and non darwinistic behaviours
