Topic: Fisher information in classical and quantum optics
Description: Fisher information is a quantity that allows the calculation of the uncertainty with which the value of a parameter can be determined. In classical and quantum optics, it is used to calculate the uncertainty with which the value of the phase in a Mach-Zehnder interferometer can be determined. Calculations of measurement uncertainty for different types of light will be performed. The results obtained using classical and quantum methods will be compared with each other.

Topic: Collective measurements for quantum communications
Description: Collective measurements are quantum measurements carried out simultaneously on multiple copies of the quantum state under investigation. They have been shown to be an invaluable tool for efficiently detecting and quantifying several key properties of quantum states, such as different entanglement measures or stronger quantum correlations. At the same time, collective measurements can be easily implemented in quantum communications networks, making them a key tool for the operation of prospective large-scale quantum networks connecting multiple users. Thus, the study of collective measurements promises interesting fundamental insights as well as results applicable to practical quantum communications.

Topic: Open quantum systems with spectral singularities and memory effects
Description: This PhD project will explore non-Markovian quantum dynamics in open quantum systems, with a particular focus on the interplay between memory effects and spectral singularities (so-called exceptional points) in non-Hermitian systems. The research will investigate few-mode quantum optical systems interacting with structured, non-Markovian environments, where time-dependent dissipation and information backflow play a crucial role. Using numerical simulations based on time-dependent Lindblad master equation and non-Markovian stochastic differential equations, the project aims to understand how spectral singularities (exceptional points) and memory effects jointly affect system dynamics and how they can be harnessed for quantum sensing applications.
