It is well known that an amplification of an optical signal is accompanied with noise. Can we amplify without any added noise? We shall present some general arguments and then given possible schemes in atomic system as well as schemes based on catalysis and quantum optical scissors circuits.
Prof. Zubairy's research interests include quantum optics and laser physics. He is the co-author of two books, one on Quantum Optics and the other on Quantum Computing Devices. Prof. Zubairy received his Ph.D. from the University of Rochester in 1978 working under the supervision of Prof. Emil Wolf. He held research and teaching appointments at the Optical Sciences Center of the University of Arizona and the Center for Advanced Studies at the University of New Mexico before joining the Quaid-i-Azam University, Islamabad, Pakistan in 1984. He served as Professor of Electronics and the founding Chairman of the Department of Electronics at the Quaid-i-Azam University. In 2000 he joined Texas A and M University where he is presently a University Distinguished Professor in the Department of Physics and Astronomy and the holder of the Munnerlyn-Heep Chair in Quantum Optics. He has received many honors including the Willis E. Lamb Award for Laser Science and Quantum Optics, Alexander von Humboldt Research Prize, the Outstanding Physicist Award from the Organization of Islamic Countries, the Abdus Salam Prize in Physics, the International Khwarizmi Award from the President of Iran, the Orders of Hilal-e-Imtiaz and Sitara-e-Imtiaz from the President of Pakistan, and the George H. W. Bush Award for Excellence in International Research. He is an elected member of the Pakistan Academy of Sciences and a Fellow of the American Physical Society and the Optical Society.
