Low-Noise Ultrafast Lasers for Robust and Scalable Quantum Systems

Quantum technologies increasingly rely on ultrafast laser systems combining low noise, precise synchronization, and long-term stability. From quantum network synchronization and photonic quantum computing to optical clock systems, laser performance directly impacts the scalability and robustness of the overall architecture.

In this talk, Pertoldi presents compact GHz ultrafast lasers and optical frequency combs designed for emerging quantum applications and will discuss the key laser characteristics required for quantum systems, including low timing jitter, amplitude and phase noise, spectral stability, and reliable long-term operation. The presentation will highlight applications including single- and entangled-photon generation, single-photon detector characterization, synchronization, and frequency-comb-based optical clock systems, showing how robust industrial laser platforms can help bridge the gap between laboratory experiments and deployable quantum infrastructure.
