报告题目：Quantum time报 告 人: Lorenzo Maccone报告时间：2025年10月17日 13:30报告地点：物理楼E100内容摘要: In textbook quantum mechanics, time is a (classical) parameter that is not described by the theory. Famously, there is no time observable, which means that there is no theoretical prescription of how to perform time measurements, much to the consternation of experimentalists who perform ti...
