Richard Hughes is a Laboratory Fellow in the Physics Division at Los Alamos National Laboratory. He is principal investigator of several projects in quantum computation and quantum cryptography. He obtained his Ph.D. in Theoretical Elementary Particle Physics from the University of Liverpool, England in 1978 and has held research positions at: Oxford University and The Queen’s College, Oxford; the California Institute of Technology; and CERN, Geneva, Switzerland. He has held distinguished visiting scientist positions at Oxford University (Dr. Lee Fellow, Christ Church, 1994) and at the University of Oslo, Norway (1993). He became a Fellow of the American Physical Society in 1999. In 2001 he was co-winner of an R&D100 Award for “Free-space quantum cryptography”. Richard has authored over 100 scientific papers on quantum field theory, the foundations of quantum mechanics, quantum cryptography and quantum computation, and leads the ARDA “Quantum information science and technology roadmap”. In his spare time he enjoys ultramarathon trail running over distances of up to 100 miles.
