Objective Novel configurations and concepts for interferometric gravitational-wave (GW) detectors will need a quantum-limited, quadrature-sensitive readout of the output signal. In principle, these requirements can be met by balanced homodyne detection (BHD), which is a well-established technique within table-top experiments in quantum optics. However, up to now no knowledge exists of whether BHD is compatible with the extreme requirements of large-scale interferometers. Within this project, I will use my knowledge of BHD to investigate its performance in interferometric setups with suspended optics, i.e. in an environment as in GW detectors. The research will cumulate in the design and construction of a monolithic BHD to be tested and used within the Sagnac Speedmeter testbed at the University of Glasgow. During my stay in Glasgow, I will benefit from the university’s highly regarded Career Development resources to increase my expertise in professional research management and leadership. At the end of my project I will have acquired substantial knowledge about suspended interferometer techniques, bridging the gap between table-top experiments and large-scale detectors. The results will pave the way for advanced quantum-noise suppression techniques in next-generation gravitational wave detectors such as the Einstein Telescope and LIGO Ultimate, providing high visibility of my research within the scientific community and leading to further career opportunities in GW astronomy Fields of science natural sciencesphysical sciencesastronomyobservational astronomygravitational wavesengineering and technologymechanical engineeringmanufacturing engineeringsubtractive manufacturingnatural sciencesphysical sciencesopticsnatural sciencesphysical sciencesquantum physicsquantum optics Keywords Gravitational Wave Detection Balanced Homodyne Readout Quantum Noise Interferometry Programme(s) H2020-EU.1.3. - EXCELLENT SCIENCE - Marie Skłodowska-Curie Actions Main Programme H2020-EU.1.3.2. - Nurturing excellence by means of cross-border and cross-sector mobility Topic(s) MSCA-IF-2014-EF - Marie Skłodowska-Curie Individual Fellowships (IF-EF) Call for proposal H2020-MSCA-IF-2014 See other projects for this call Funding Scheme MSCA-IF - Marie Skłodowska-Curie Individual Fellowships (IF) Coordinator UNIVERSITY OF GLASGOW Net EU contribution € 195 454,80 Address UNIVERSITY AVENUE G12 8QQ Glasgow United Kingdom See on map Region Scotland West Central Scotland Glasgow City Activity type Higher or Secondary Education Establishments Links Contact the organisation Opens in new window Website Opens in new window Participation in EU R&I programmes Opens in new window HORIZON collaboration network Opens in new window Total cost € 195 454,80
