Scattering Loss in Precision Metrology due to Mirror Roughness

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Yehonathan Drori, Johannes Eichholz, Tega Edo, Hiro Yamamoto, Yutaro Enomoto | Summary: Optical losses degrade the sensitivity of laser interferometric instruments. They reduce the number of signal photons and introduce technical noise associated with diffuse light. In quantum-enhanced metrology, they break the entanglement between correlated photons. […]
