Precision measurements have been a primary driving force for advancing modern science. In particular, km-scale optical interferometers at their quantum limit led to the transformative observation of gravitational waves. Microwave cavities, resonant electric circuits, and optical interferometers are currently searching for axion dark matter with unprecedented sensitivity and are limited by quantum effects. How can we further advance precision measurements? In this project, you will explore a new paradigm using quantum amplification. You will entangle a 30-nm thick silicon nitride membrane at cryogenic temperatures with laser light to enhance interferometric measurements. The goal of the project is to find the membrane design that makes quantum amplification possible. You will design and produce the membrane, commission a laser interferometer with the membrane, and measure quantum enhancement. You will learn the principles of quantum optics, laser interferometry, cryogenic systems, and control theory. The project will be supervised by Professor Denis Martynov.
Research councils STFC and EPSRC. Note that applications from overseas students will also be considered. It would be ideal if international students could bring additional funding, such as scholarships or fellowships, to cover the gap in fees between domestic and international students. Some counties, such as China, have specific scholarships for the purpose, such as fellowships from Chinese Scholarship Council.
