The Quantum-Enhanced Space-Time (QUEST) experiment consists of a pair of colocated power recycled Michelson interferometers, each designed to have a broadband, shot-noise-limited displacement sensitivity of $2×{10}^{−19}\text{ }\text{ }\mathrm{m}/\sqrt{\mathrm{Hz}}$ from 1 to 200 MHz. Here, we prese… [Phys. Rev. Lett. 135, 101402] Published Wed Sep 03, 2025
