Entanglement, the most puzzling feature of quantum theory, is at the heart of the speedup promised by quantum technologies. Quantum interferometry exploits the engineering of particle-entangled states to estimate time, forces, accelerations and lengths with a sensitivity exceeding — in principle by several orders of magnitude — the bound of classical interferometers. Our research focuses on the deep implications of entanglement and its realistic implementation for precision measurements with light and matter.
