Towards the Quantum Limit: Update from the AEI 10-meter Prototype — •Conor Mow-Lowry and the 10m prototype team — Max-Planck Institute for Gravitational Physics, Hannover, Germany

At the Albert Einstein Institute in Hannover we are building a prototype facility capable of housing experiments that will probe the boundaries of interferometric sensitivity. Our core experiment is a Fabry-Perot Michelson interferometer designed to reach the Standard Quantum Limit (SQL), the point where quantum radiation pressure noise and photon shot noise are equal. From there we can investigate techniques to surpass this limit.

Many of the infrastructure components of our facility are themselves research projects, borrowing from developments in space-based metrology and from the most sensitive devices in the world, interferometric gravitational-wave detectors. I will describe the status of the 10-meter project with a focus on the many interesting challenges between us and meeting our design goals.
