关于时间概念的问题

量子历史理论的概念分析

Conceptual analysis of quantum history theory

我们给出了一些概念的正式内容，这些概念自然来自于一致的历史方法（CHA），而这些概念在理论的标准表述中并不形式化。结果（扩展）的概念基础是用来执行一个正式的，概念上透明的分析，在CHA的一些有争议的问题。结果排除了Kent的相反推论所引起的问题，但该理论的某些规定不能维持。

量子力学中的到达时间概念

The time of arrival concept in quantum mechanics

讨论了量子力学中到达时间的概念及其形式化。基于轨迹，量化规则，时间算子，相空间技术，更新方程或操作程序的不同方法进行审查或提出。开放的问题和松散的结束指出。

基于量子信息概念的经典可逆电路Toffoli门个数的下界

Lower bound on the number of Toffoli gates in a classical reversible circuit through quantum information concepts

在一个经典的可逆电路中找到一个下界的Toffoli门的数量的问题得到解决。提出了一种基于量子信息概念的方法。该方法仅涉及量子信息的概念-不需要实际的物理量子计算机。以经典Shannon数据压缩为例说明了该方法。

关于时间之箭的问题

Open Questions regarding the Arrow of Time

讨论了经典物理学、量子物理学、宇宙学和量子引力中关于时间之箭的概念问题。特别注意的是量子不确定性的动态作用，并对各种概念的永恒性。

Questions on the Structure of Perfect Matchings inspired by Quantum Physics

We state a number of related questions on the structure of perfect matchings. Those questions are inspired by and directly connected to Quantum Physics. In particular, they concern the constructability of general quantum states using modern photonic technology. For that we introduce a new concept, denoted as inherited vertex coloring. It is a vertex coloring for every perfect matching. The colors are inherited from the color of the incident edge for each perfect matching. First, we formulate the concepts and questions in pure graph-theoretical language, and finally we explain the physical cont…

Conceptual understanding through efficient inverse-design of quantum optical experiments

One crucial question within artificial intelligence research is how this technology can be used to discover new scientific concepts and ideas. We present Theseus, an explainable AI algorithm that can contribute to science at a conceptual level. This work entails four significant contributions. (i) We introduce an interpretable representation of quantum optical experiments amenable to algorithmic use. (ii) We develop an inverse-design approach for new quantum experiments, which is orders of magnitudes faster than the best previous methods. (iii) We solve several crucial open questions in quantu…
