Daniel A. Lidar is a Professor of Electrical Engineering and Chemistry, and the Director and co-founder of the USC Center for Quantum Information Science & Technology (CQIST), notable for his research on control of quantum systems and quantum information processing.



He is class of 1986 graduate of the Armand Hammer United World College of the American West. He received his B.Sc. from the Hebrew University of Jerusalem in 1989, performed national service from 1989–1993, received his M.Sc. in 1993, and obtained his PhD under Robert Benny Gerber and Ofer Biham, 1997, with a thesis entitled Structural Characterization of Disordered Systems also from the Hebrew University of Jerusalem.


In 1997-2000, he was a postdoc at UC Berkeley, having been awarded Rothschild Foundation and Fulbright Program fellowships (the latter of which he declined); in 2000-2005, he was an assistant professor and then later an associate professor of Chemistry at the University of Toronto, with cross-appointments in Physics and Mathematics. While at Berkeley, he was a collaborator with Magiq Technologies[1] and while at Toronto he collaborated with D-Wave Systems.[2][3] He moved to the University of Southern California in 2005 as an associate professor of Chemistry and Electrical Engineering, with a cross-appointment in Physics. Lidar's research interests lie primarily in the theory and control of open quantum systems, with a special emphasis on quantum information processing. His past interests include scattering theory and fractals.


He is the recipient of a number of awards and honors, including a Sloan Foundation Fellowship, the Young Explorer Award given by the Canadian Institute for Advanced Research for the top 20 researchers in Canada under age 40, and the John Charles Polanyi Prize in Chemistry awarded by the Ontario Council of Graduate Studies.[4] He is a 2007 Fellow of the American Physical Society[5] and Senior Member of the IEEE. He is listed as one of the top 20 authors of the decade 2000-2009 in Quantum Computing by Thomson Reuters' Sciencewatch. In 2009 he was elected an Outstanding Referee of the American Physical Society.


Lidar's research in quantum information processing has focused primarily on methods for overcoming decoherence. He wrote some of the founding papers on decoherence-free subspaces, most notably his widely cited paper "Decoherence-free subspaces for quantum computation",[6] and their generalization, noiseless subsystems. These contributions were noted in his APS Fellow citation.[7] He has also made major contributions to dynamical decoupling, in particular the invention (with his student Kaveh Khodjasteh) of the concatenated dynamical decoupling (CDD) method.[8] He has made a proposal to protect adiabatic quantum computation against decoherence, using dynamical decoupling, one of the only proposals to date dealing with error correction for the adiabatic model.[9] Lidar has also worked on quantum algorithms, having written some of the pioneering papers in the subject on simulation of classical statistical mechanics[10] and quantum chemistry.[11] In his Ph.D. work he made a widely cited observation on the limited scaling range of empirically observed fractals,[12] which led to a lively exchange with Benoit Mandelbrot.[13]


He holds four U.S. patents in the area of quantum computing. [1] [2] [3] [14]
