Sintayehu Tesfa is assistant professor at Jazan University where he teaches general physics courses and adjunct professor at Adama and Addis Ababa Universities where he advises students and teaches quantum optics. Earlier, he taught quantum optics at Dilla University and he has been a guest scientist at Max Planck Institute of complex systems, Dresden. Since last 15 years, he has been working on quantum optics and quantum information with emphasis to exploring nonclassical properties of light. Particularly, he is one of the pioneers in the study of the quantification of the degree of quantum entanglement and discord of the light generated by nonlinear and linear optical sources such as parametric up-conversion and correlated emission laser.
