11. His research centres on the areas of atom physics, quantum optics , and laser physics. 12. This was the case considered by Einstein, and is nowadays used for quantum optics . 13. Sudarshan's most significant work might be his contribution to the field of quantum optics . 14. His research interests are quantum entanglement and quantum optics . 15. Quantum optics is the study of the nature and effects of light as quantized photons.16. Such investigations can be extended to studying new intriguing effects emerging in semiconductor quantum optics . 17. The SLEs can also be used as a systematic starting point for semiconductor quantum optics . 18. A major subfield of modern optics, quantum optics , deals with specifically quantum mechanical properties of light. 19. His research is focused on quantum optics , the quantum theory of information and quantum many-body physics. 20. These vacuum fluctuations are responsible for many interesting phenomenon including the Lamb shift in quantum optics .
