When applied to practical problems, the very laws of quantum mechanics can provide a unique resource to beat the limits imposed by classical physics: this is the case of quantum metrology and high-precision sensing. Here we review the main results obtained in the recent years at the Quantum Technology Lab of the Department of Physics “Aldo Pontremoli” of the University of Milan, also in collaboration with national and international institutions. In particular we focus on the application of continuous-variable optical quantum states and operations to improve different fields of research, ranging from interferometry to more fundamental problems, such as the testing of quantum gravity.

具有连续可变光学状态的高精度创新感测

当应用于实际问题时，量子力学定律可以提供独特的资源来克服经典物理学所施加的限制：这是量子计量学和高精度传感的情况。在这里，我们与国家和国际机构合作，回顾了近年来在米兰大学物理系“ Aldo Pontremoli”的量子技术实验室获得的主要结果。特别是，我们专注于应用连续变量光学量子态和操作来改善不同的研究领域，从干涉测量到更基本的问题，例如量子引力的测试。
