Jonathan P. Dowling is an Irish-American Co-Director of the Horace Hearne Institute for Theoretical Physics, and also a Hearne Chair in Theoretical Physics at the Department of Physics and Astronomy, both at Louisiana State University. He is known for his work on quantum technology, particularly for exploiting quantum entanglement (in the form of a NOON state) for applications to quantum metrology, quantum sensing, and quantum imaging (particularly as the inventor of quantum lithography). He has also made contributions to quantum information theory, the field of photonic crystals, and the foundations of quantum electrodynamics. Dowling is one of the founders of the US Government program in quantum information processing.
Jonathan P. Dowling holds dual citizenship from Ireland and the USA. He obtained his BSc in Physics at the University of Texas at Austin then attended graduate school at the University of Colorado at Boulder, where he obtained an MSc in Applied Mathematics, a MSc in Physics, and a PhD in Mathematical Physics ; his advisor was Asim Orhan Barut.
He then moved to the Max-Planck-Institute of Quantum Optics as a postdoctoral researcher in the group of Herbert Walther, where he also collaborated with Marlan Scully. After that, he joined the quantum optics group of Charles M. Bowden at United States Army Aviation and Missile Command in Huntsville, Alabama, as a United States National Research Council Post-Doctoral Research Associate, where he was eventually promoted to Research Physicist of the United States Army Aviation and Missile Research, Development, and Engineering Center.
After this, he moved to take a position as Research Scientist at the Senior Level in the Quantum Computing Technologies Group at the NASA Jet Propulsion Laboratory, where he was promoted to Group Supervisor and Principal Scientist of this JPL group. After this position, he moved to Louisiana State University to take up his current posts there.

Dowling has authored over 170 scientific publications  in quantum electrodynamics, quantum optics, quantum sciences, and quantum technology. His publications have been cited over 8,000 times, with an average number of 50 citations per paper, with a Hirsch index over 43. Over 26 papers have been cited over 100 times each. He also holds seven US Patents.
Dowlings's three most-cited research papers are on the topics of quantum lithography,  optical switching in photonic crystals,  and the photonic band-edge laser.  Dowling is also known for a series of papers on the quantum theory of atomic spontaneous emission and other quantum electrodynamics effects in optical micro-cavities and photonic crystals. 
His recent work has focused on optical quantum computing,  as well as quantum metrology, quantum imaging,  and quantum sensing  —all with the optical NOON state  and other related quantum entangled states.
Dowling is the author of a new popular science book, Schrödinger's Killer App: The Race to Build the World's First Quantum Computer , (Taylor & Francis, 2013).
Told from a government insider's point of view, this volume is the fascinating story of the quest to develop a quantum computer. Using non-technical language, amusing personal anecdotes, and easy-to-follow analogies, the book leads us from the beginnings of quantum information technology to the present time.
