Topological materials are promising for ultra-low power and quantum computers

Bi2Sb3: -First known 3D topological insulator. -Highly complex surface states. Properties. Insulating materials that conduct electricity through gapless surface states. The surface states are topologically protected , which means that they cannot be destroyed by impurities or imperfections. Topological insulators require two conditions: Time reversal symmetry. Strong spin–orbit interaction, which occurs in heavy elements such as Hg and Bi. Where do the surface states come from? How did they originate. How were they predicted with theory? (Find the papers) Applications. They’re cool! Integrated circuit technology. Minimize power dissipation. Spintronics. Error tolerant quantum computation. Scattering may alter, but won’t destroy conductive surface states.

The theoretical underpinnings for these materials, called “topological” because they are described by properties that remain intact when an object is stretched, twisted or deformed, led to the awarding of the Nobel Prize in physics in 2016 to F. Duncan M. Haldane, Princeton University’s Sherman Fairchild University Professor of Physics, …

NASA and DOD thrust on Software Assurance to assure to assure high quality, safety, securety and reliability of mission-critical systems


Computers are increasingly being introduced into safety-critical systems, and, as a consequence, have been involved in accidents. Between June 1 985 and January 1987, six known accidents involved massive overdoses by the Therac-25 – with resultant deaths and serious injuries. The cause was attributed to the errors in control program, …

US DOD’s JUMP program to develop high performance, energy efficient and secure microelectronics for dominance in future Battlefield Internet of Things


The Joint University Microelectronics Program (“JUMP”), is a collaborative effort between the Department of Defense, U.S. universities and the industrial participants with a goal to substantially increase the performance, efficiency, and capabilities of broad classes of electronics systems for both commercial and military applications. The collaborative, multidisciplinary, multi-university consortium will …
