Quantum resource states such as Schrödinger Cat States and Entangled Coherent States or biphoton states are crucial components of various quantum technologies like Quantum Computing, Quantum Metrology, Quantum Imaging, and Quantum Sensing. For example, Cat States enable precision measurements of physical quantities beyond classical limits in metrology, while they can be used for quantum error correction in Quantum Computing. Entangled Coherent States, where multiple light modes are entangled, increase the sensitivity of measurement instruments by reducing the effects of quantum noise. These states are particularly useful as they allow for the detection of previously invisible details and improve the detection of weak signals. Our research group focusses on developing protocols for the efficient generation of such resource states as well as to explore potential applications.
Schema Gaussian Boson Sampler

In the field of photonic quantum simulations, a special focus of our group is on Gaussian Boson Sampling. This method allows us to simulate complex quantum systems and investigate phenomena that are not efficiently computable with classical computers, based on the principle of quantum interference of photons. Our research aims to gain insights into quantum chemistry and complex optimization problems using Gaussian Boson Sampling.
Quantum Imaging
Quantum Imaging based on "Undetected Photon Schemes" is an innovative technique that produces images from photons that have not interacted with the object. Correlated photon pairs are used for this method, where only one of the photons interacts with the object to be examined. The other photon, which has not interacted with the object, is measured instead. Due to the correlations between the two photons, information about the object can be obtained from the measurements of the undetected photon. This allows for obtaining information about the object that would not be accessible with traditional imaging methods, such as the structure of light-sensitive materials or biological samples, without damaging them.
