| Michigan Tech News Lessons from the Brain: Toward an Intelligent Molecular Computer April 26, 2010— A team of researchers from Japan and Michigan Technological University has built a molecular computer using lessons learned from the human brain. Physicist Ranjit Pati of Michigan Tech provided the theoretical underpinnings for this tiny computer composed not of silicon but of organic molecules on a gold substrate. “This molecular computer is the brainchild of my colleague Anirban Bandyopadhyay from the National Institute for Materials Science,” says Pati. Their work is detailed in “Massively Parallel Computing on an Organic Molecule Layer,” published April 25 online in Nature Physics. [...] The researchers made their different kind of computer with DDQ, a hexagonal molecule made of nitrogen, oxygen, chlorine and carbon that self-assembles in two layers on a gold substrate. The DDQ molecule can switch among four conducting states—0, 1, 2 and 3—unlike the binary switches—0 and 1—used by digital computers. “The neat part is, approximately 300 molecules talk with each other at a time during information processing,” Pati says. “We have mimicked how neurons behave in the brain.” “The evolving neuron-like circuit network allows us to address many problems on the same grid, which gives the device intelligence," Pati says. |

Quantum Modeling of Nanoscale Materials for Electronics |
 | Nanoscience is an emerging research area in the 21st century and holds the key to the various physical phenomena that occur in nature as well as in our day to day life. Our motto has been to understand and learn this very basic science and improve upon it whatever we can for the betterment of the mankind. |

 A tree never goes to school but performs particularly advanced supercomputing in its leaves, so does our brain without a single logic gate. Ants in the soil, birds in the sky do not have brain but still develop intelligence. Therefore lots of idiots can develop massive intelligence working together, or massive parallel operations can generate intelligence in a single control unit. [...] Our objective is to demonstrate that these concepts are not merely theoretical formulation, rather practically realisable at nano-scale using simple molecules in simple experiments. |
