Generation of Squeezed States in Erbium-Doped Fiber for Quantum-Enhanced Dual-Comb Spectroscopy

This project focuses on improving the sensitivity of advanced laser measurement tools, known as dual-comb spectrometers, by using quantum mechanics to reduce noise below standard physical limits. During a research internship at the University of Colorado Boulder, the student will learn to generate “squeezed” states of light and aim to adapt this cutting-edge technology to cost-effective fiber lasers, making high-precision sensing more widely accessible for applications like environmental monitoring. This collaboration benefits both institutions by combining the University of Colorado’s world-class experimental facilities in quantum optics with Université Laval’s expertise in signal processing, ultimately allowing the latter to import rare engineering knowledge to build Québec’s first quantum-enhanced spectroscopy setup.
