Foundations and applications of quantum causality

该项目旨在研究量子世界中因果关系的本质。随着专用量子设备的出现，对新型量子协议的需求具有迫切的技术和经济意义。使用跨学科的方法，该项目将探索量子优势与经典量子现象的经典模拟中微调的基本需求相关的假设。预期成果包括微调的资源理论提供了一个物理图像，以指导量子技术，新的基本测试的非经典性，并在我们的理解量子现实和因果关系的性质的重大理论和哲学进步。

This project aims to investigate the nature of causality in the quantum world. With special-purpose quantum devices on the horizon, the need for novel quantum protocols is of urgent technological and economic significance. Using interdisciplinary methodologies, this project will explore the hypothesis that quantum advantage is associated to a fundamental need for fine-tuning in classical simulations of quintessentially quantum phenomena. Expected outcomes include a resource theory of fine-tuning providing a physical picture to guide quantum technologies, new fundamental tests of nonclassicality, and significant theoretical and philosophical advances in our understanding of the nature of quantum reality and causality.
