Foundations of Quantum Theory

该项目将研究目前在量子理论基础上研究的三个主题之间的联系：“超级观察者”（也称为扩展的维格纳朋友场景），量子因果模型（特别是那些具有不确定因果顺序的模型）和广义概率理论。目的是更深入地理解量子理论中的测量和因果关系，并探索这种理解可能对量子理论的任何后继者施加什么约束。

This project will investigate connections between three topics currently researched in the foundations of quantum theory: "superobservers" (also known as extended Wigner's friend scenarios), quantum causal models (especially those with indefinite causal order), and generalised probabilistic theories. The aim is to gain a deeper understanding of measurements and causality in quantum theory, as well as to explore what constraints this understanding might impose on any successor to quantum theory.
