Khatri, Kish research featured in New Scientist Tech

The collaborative research of Dr. Laszlo Kish and Dr. Sunil Khatri has been featured in an article, "Breaking the noise barrier: Enter the phonon computer," in New Scientist Tech.Dr. Laszlo Kish and Dr. Sunil KhatriKish (pictured on the left), a professor in the Department of Electrical and Computer Engineering at Texas A&M University, and Khatri (right), an associate professor in the same department, have been researching noise-based logic, computing and brain circuitry. Their work on theoretical properties of a logic system that uses large-scale random noise signals was part of the New Scientist Tech article, along with several other researchers' work. Their idea is to represent the 0s and 1s of digital signals not by using voltage levels as in conventional computers, but by using independent noise signals instead.Kish and Khatri's research shows that noise has a pattern that is characteristic of its source. It is this that makes it possible to keep track of different noise signals and compute with them. Any background noise will be different from the noise signals being used for computation, making it possible to "subtract" its effect.In the article they also claim that noise signals can be superimposed and sent through a single wire without losing their identity, making it possible to carry out two or more calculations simultaneously. This kind of logic is especially suited to certain types of calculation, but they are still trying to quantify exactly how this can be realized in practice. Eventually these findings could provide fast, low-power computing, they say.Kish directs the Fluctuation and Noise Exploitation Laboratory in the department and also is a researcher in the Electrical and Computer Engineering Division of the Texas Engineering Experiment Station, a member of The Texas A&M University System. TEES administers Kish's research. He received his doctoral degree in solid state physics from the University of Szeged. His general research interests include the study of laws, limits and applications of electronic noise processes for sensing, communication and information processing. Such applications are fluctuation-enhanced sensing, unconditionally secure communications, zero-signal-power communications, and noise-based logic.Honors include being the recipient of the year 2001 Benzelius Prize of the Royal Society of Science of Sweden for his activities on chemical sensing and receiving a Doctor of Science (Physics) from the Hungarian Academy of Science in 2001. He has also received the Doctor Honoris Causa title from Uppsala University, Sweden, and will officially accept it in a formal January 2011 ceremony.Khatri completed his Ph.D. from the University of California, Berkeley, in 1999. Before this, he worked with Motorola Inc. on the designs of the MC88110 and PowerPC 603 RISC microprocessors. He obtained his M.S. from the University of Texas at Austin and his B.Tech. from the Indian Institute of Technology at Kanpur.Khatri's research is in the areas of VLSI CAD, VLSI Design (including the design of resilient circuits, extreme low power circuits and efficient on-chip clocking), and cross-disciplinary topics (including applications of VLSI CAD and design approaches to the areas of communication, genomics, radiation detection, embedded systems, and networking). Honors include receiving the Outstanding Faculty Award from the department and the college-level Association of Former Students Distinguished Achievement Award in teaching. Khatri and his students have received four best paper awards and three other best paper nominations. Read the article or learn more about Kish and Khatri's joint research.
