An Introduction to Quantum Computing
12 Sep 2008 | Online Presentations | Contributor(s): Edward Gerjuoy
Quantum mechanics, as formulated more than 80 years ago by Schrodinger, Heisenberg, Dirac and other greats, is a wholly sufficient foundation for its modern interrelated subfields of quantum computation (qc) and quantum information (qi), which generally are lumped together into a single subfield …

Hierarchical Temporal Memory: How a New Theory of Neocortex May Lead to Truly Intelligent Machines
12 Dec 2007 | Online Presentations | Contributor(s): Jeff Hawkins
Coaxing computers to perorm basic acts of perception and robotics, let alone high-level thought, has been difficult. No existing computer can recognize pictures, understand language, or navigate through a cluttered room with anywhere near a child's facility. Following nature's example, Jeff …

Electrons in Two Dimensions: Quantum Corrals and Semiconductor Microstructures
04 Dec 2007 | Online Presentations | Contributor(s): Eric J. Heller
The images generated by a scanning tunneling microscope are iconic. Some of the most famous are Don Eigler’s quantum corrals, which reveal not only the guest atoms on a surface but especially the interference patterns of electrons shuttling back and forth along the surface. To understand the …

New Dimension in Performance: Harnessing 3D Integration Technology
29 Nov 2007 | Online Presentations | Contributor(s): Kerry Bernstein
Despite generation on generation of scaling, computer chips have remained essentially 2-dimensional. Improvements in on-chip wire delay, and in the total number of inputs and outputs has not been able to keep up with improvements to the transistor, and its getting harder and harder to hide it! 3D …
