2015
April 26, 2015 — QST students Jonathan P. Olson and Evan J. Rabeaux and Professor Jonathan P. Dowling have published their research on quantum metrology in Physical Review Letters. Their proposal requires a bank of photon sources, undergoing an evolution within an interferometer, followed by photodetection, and enables precise measurements, beyond what is possible classically.
March 24, 2015 — Congratulations to PhD candidate Kaushik Parasuram Seshadreesan, who has successfully defended his PhD thesis and accepted an offer for a summer internship at the National Institute of Information and Communications Technology in Tokyo, Japan followed by a postdoctoral fellowship at the Max Planck Institute for the Science of Light in Erlangen, Germany under the supervision of Gerd Leuchs.
February 23, 2015 — Postdoctoral Scholar Xiaoting Wang joins our research group. He was previously a postdoctoral research affiliate with Professor Seth Lloyd at the Massachusetts Institute of Technology and a postdoctoral research fellow with Professor Kurt Jacobs at the University of Massachusetts Boston. He received his PhD in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge under the supervision of Professor Sophie Schirmer.
2014
October 24, 2014 — Assistant Professor Mark M. Wilde's research on quantum key distribution has been published in a recent issue of Nature Communications. The work establishes a fundamental bound on the rate at which quantum secured information can be communicated over an optical communication channel, such as a fiber optic or free space link. The U.S. government is now using the bound as a benchmark to assess quantum key distribution protocols.
September 18, 2014 — Professor Jonathan P. Dowling's research on a time-bin encoded boson-sampling architecture has been published in Physical Review Letters. The work shows how to reduce the required number of optical elements in building a boson-sampling device.
August 10, 2014 — Congratulations to PhD candidate Bhaskar Roy Bardhan, who has accepted an offer to begin in November 2014 as a postdoctoral fellow in the Research Laboratory of Electronics at the Massachusetts Institute of Technology under the supervision of Jeffrey H. Shapiro.
May 21, 2014 — Congratulations to PhD candidate Kaushik Seshadreesan, who has received the 2014-2015 Dissertation Year Fellowship from the Graduate School of LSU.
April 30, 2014 — The National Science Foundation has awarded Professor Jonathan P. Dowling a Theoretical, Atomic, Molecular, and Optical division single-investigator grant. The project is entitled “The Rise of the Boson-Sampling Quantum Computer and The Renaissance of the Linear Optical Quantum Interferometer” and will run from June 15, 2014 until May 30, 2017.
April 30, 2014 — The National Science Foundation has awarded Assistant Professor Mark M. Wilde an Early Career development grant. The project is entitled “Theoretical and practical aspects of quantum communication protocols” and will run from May 15, 2014 until April 30, 2019.
January 10, 2014 — Postdoctoral Scholar Thomas Cooney joins our research group. He was previously in the research group “Mathematics and Quantum Information” with David Perez-Garcia at the Universidad Complutense de Madrid. He received his PhD in mathematics in 2010 from the University of Illinois at Urbana-Champaign.
2013
December 30, 2013 — Assistant Professor Mark M. Wilde's research on an information-theoretic formulation of the Heisenberg uncertainty principle has been accepted for publication in Physical Review Letters. The research quantifies with entropies the fundamental trade-off between measurement error and disturbance in any measurement of a quantum system.
December 16, 2013 — Professor Jonathan Dowling and the Quantum Science and Technologies group are featured in an article on the LSU web site.
November 5, 2013 — Congratulations to Bhaskar Roy Bardhan, who has received the Coates Scholar Research Grant from the LSU Graduate School.
November 4, 2013 — Assistant Professor Mark M. Wilde's research on time travel and quantum cloning has been accepted for publication in Physical Review Letters. Wilde and his coauthors show that it is possible to violate the no-cloning theorem of quantum mechanics if one has access to a closed timelike curve (a time machine) that behaves according to a model established in 1991 by David Deutsch.
September 15, 2013 — Professor Jonathan P. Dowling has been awarded an Army Research Office grant entitled “From Quantum Computing to Quantum Sensing”.
June 10, 2013 — Assistant Professor Mark M. Wilde's textbook Quantum Information Theory is published by Cambridge University Press. The book “develops the subject 'from the ground up', covering classical results as well as major advances of the past decade.” Available at Amazon, Cambridge University Press, and on Google Books.
May 7, 2013 — Professor Jonathan P. Dowling's book Schrodinger's Killer App: Race to Build the World's First Quantum Computer is published by Taylor and Francis. The book “presents an inside look at the government’s quest to build a quantum computer capable of solving complex mathematical problems and hacking the public-key encryption codes used to secure the Internet.” Available at Amazon and on Google Books.
