Quantum Optics & Spectroscopy

Quantum optics is a dynamic research field concerned with the properties of individual quanta of light, called photons, and their interactions with atomic-scale systems. It comprises the fundamental understanding of the basic processes encountered in spectroscopy, the working principle of lasers, as well as applications of quantum light for quantum technologies such as secure communication, or for interconnecting future quantum computers into quantum networks.

KSOP Research Area II covers experimental and theoretical research on fundamental quantum optics phenomena and their applications, as well as the development and application of advanced spectroscopic methods.

One focus is the investigation of materials that can serve as quantum light sources and optically addressable quantum bits. To control light-matter interactions, engineered photonic devices are developed, ranging from optical microcavities to nanoplasmonic antennas and integrated optical circuits. Expanding a detailed theoretical understanding of novel materials and photonic devices is key to these developments. 

On the other hand, advanced spectroscopic methods which can probe sample composition and properties play a crucial role in helping to uncover and characterize novel quantum and nonlinear phenomena in many fields, ranging from molecular photophysics to atmospheric chemistry. At KSOP, methods are developed and applied, including ultrafast spectroscopy, remote sensing, and highly spatially resolved imaging. Such advanced techniques are essential for expanding research horizons, e.g., in materials science and nanotechnology.
