P1703 Physics – Optics and Optoelectronics

Highly nonclassical light is a necessary resource for upcoming quantum technology. Highly efficient generation of Fock states and their controllable superposition is a current bottleneck of quantum optics. It is required for major applications of quantum technology like quantum metrology and quantum communication. Current experimental platforms generate typically attenuated versions of such the states with a background noise or they are limited to the generation of maximally three-photon state with a negative Wigner function. It therefore important to (i) develop methodology of detection and quantification of multi-photon highly nonclassical light, (ii) test the methodology on existing sources from nonlinear optics, atoms and solid state emitter, (iii) propose and model advanced sources based on the best current candidates and finally,
(iv) apply this methodology to that novel sources of light. These are sequentially scientific goals of this PhD study. PhD study will be in theoretical quantum optics and quantum engineering with atoms and solid state systems. It continues the existing research line, specifically, running projects on generation, detection and identification of highly nonclassical light from many incoherent independent emitters (atoms, ions, quantum dots etc.).  The PhD student is expected to participate in reaching the research goals of the Center of Excellence of the Czech Science Foundation. The theoretical work of PhD student will be focused on extended numerical simulation of coherent interaction of light with many emitters for different experimental platforms, efficient production and detection of nonclassical light and its applications in quantum metrology and quantum communication. Theoretical proposals will be followed by immediate experimental tests, inside the Center of Excellence and in cooperation with foreign labs. PhD study will be co-supervised by senior PhD student and postdoc.
