What is Quantum Optics?
Quantum optics is the study of light at the level of individual photons and how these photons interact with matter. It explains effects that classical optics cannot, such as entanglement, photon antibunching, squeezed light and quantum interference. These effects are the foundation of quantum computing, quantum communication, quantum sensing and quantum networking.

Why is Time Tagging important for Quantum Optics?
Most quantum optics experiments depend on knowing exactly when each photon arrives, not only how much light there is. Swabian Instruments Time Taggers record photon arrival times with picosecond resolution, high throughput and very low timing jitter, using time-correlated single photon counting (TCSPC). This makes it possible to measure photon correlations, coincidence events and temporal dynamics from extremely weak signals, which is what entanglement verification, HBT and HOM measurements require. Where an experiment also needs precise control and synchronization of lasers, detectors or gates, the Pulse Streamer Series provides an easy-to-use solution.
