Optical and microwave photonics for quantum science and technology

Responsible Mikkel Ejrnaes

The light-matter interaction science is the core of the activities of this research area, which focuses on how the application of innovative materials and devices can advance quantum sciences and technologies.

The understanding of a controlled light/matter interaction will lead to a wave of new functionalities and technologies based on quantum components that on one hand uses solid state devices to control the quantum nature of light and on the other hand uses light to control the quantum nature of solid state devices.

Our research activity is multidisciplinary in what combines condensed matter physics and materials science with microwave quantum optics and laser physics. In this sense, it helps pushing the boundaries of what can be envisaged in emerging fields and technologies that are based on new materials and microwave quantum optics as well as on devices with novel functionalities.
