This research aims to realise measurements below the Standard Quantum Limit (SQL) using advanced quantum optic and opto-mechanical techniques. This is of fundamental interest as the SQL is yet to be observed for a macroscopic object. It is also of particular significance to second generation gravitational wave detectors which are expected to be limited by the SQL. This project will develop an opto-mechanical sensor capable of achieving SQL sensitivity as well as develop and test techniques to surpass the SQL. These techniques will be directly applicable to long base-line gravitational wave detectors.

本研究旨在利用先进的量子光学和光机械技术实现标准量子极限（SQL）以下的测量。这是一个基本的兴趣，因为SQL还没有被观察到的宏观对象。这对受到SQL限制的第二代引力波探测器也有特别的意义。该项目将开发一种能够实现SQL灵敏度的光机械传感器，并开发和测试超越SQL的技术。这些技术将直接应用于长基线引力波探测器。
