1 postdoctoral research position
in a research project Employing multiphoton quantum interference for selected quantum information processing tasks
funded by (Polish) National Center of Science (2019/34/E/ST2/00273)

Terms of employment
Selected candidate will be employed as full-time researcher (pol. adiunkt). The duration of employment is for 23 months. The expected starting date is around May/June 2023. The offered salary approx. 7000,00 PLN gross/month.

Description of the project
The goal of the project is to deepen our understanding of multiphoton quantum interference, especially in the time domain. Quantum interference is one of the most intriguing phenomena in nature and one of the most important resources of quantum technologies. In the case of temporal platform, a train of narrow single-photon pulses undergo dispersion in a nonlinear medium. Individual pulses start to overlap and interfere. In this project we study this interference towards its applications in quantum computations and quantum simulations of topological materials. This goal is motivated by results obtained in 2019 by Dr. hab. Stobi ska and her collaborators. The first is theoretical and experimental investigation of quantum interference of multiphoton Fock states on a beam splitter and demonstration it instantaneously computes a Quantum Fourier Kravchuk Transform (QKT). This allows one to use this device as an efficient, specialized quantum computer with vast number of applications. The second result is to show that such multiphoton quantum interference enables fast quantum simulations of topological materials, which are characterized by unusual symmetries. These findings constitute starting points for the current project. The project consists of three fascinating Objectives which cover theoretical and experimental study of multiphoton quantum interference, finding links between various optical systems and mathematical operations (transforms) they realize and performing quantum simulations of materials which exhibit topological phase transitions. The results will allow us to understand the essence of complex quantum interference, to systematically enhance the palette of applications of quantum photonic systems and to investigate topological phenomena in new materials.
