Seth Lloyd is Nam P. Suh professor of mechanical engineering and of physics at MIT. Professor Lloyd’s research focuses on problems of information and complexity in the universe. He was the first person to develop a realizable model for quantum computation and is working with a variety of groups to construct and operate quantum computers and quantum communication systems. Professor Lloyd has worked to establish fundamental physical limits to precision measurement and to develop algorithms for quantum computers for pattern recognition and machine learning. Professor Lloyd’s work on complex systems currently focuses on transitions between stability and instability in complex dynamical systems. He is the author of more than two hundred scientific papers as well as of the book Programming the Universe (Knopf, 2004).
