Scientists working on chips now, but warn physics is not yet sound
San Francisco, CA -- (SBWIRE) -- 02/11/2013 -- Someday in the future, computers that are thousands of times faster than the units we use now could be at our disposal. Why would someone want that? Scientists from Georgia State University in the United States and Max Planck institute for Quantum Optimism in Germany have introduced a new process for the binary state that forms the basic computing nature.
By utilizing an insulator that is called dialectics, scientists found that they could process signals at a called a femtosecond, which is far beyond the capability of the current forms of supercomputers. Current computers have the ability to process at nearly 3 billion cycles per second; but, the new form make it possible for the machines to run at petahertz. That would allow for over a million-billion cycles per second.
Those who find this to be a surefire investment for the computer should hold off on putting their life investments into any company looking into the technology, however. The system that would facilitate such work is not yet created, and there is no complete chip or working process as of now.
"There's quite a gap between observing an effect and its implementation in a computer," says postdoctoral researcher Nicholas Karpowicz, who worked on the project at the Max Planck Institute. "In the near term we have to do much more."
John Gustafson, chief product architect at chip manufacturer AMD, points out that a computer is only as fast as its slowest part. "If you make every transistor 'infinitely' fast it'd still be so limited by the speed of its wires you'd only see a few per cent increase in performance," he says.
There are multiple changes to the chips and their design in order to bring the world of computing a chip with 10,000 more powerful capabilities. Further miniaturization and physics management to handle the heat produced is just one of the obstacles to overcome.
"We can print billions of transistors on a single chip, but if we try to operate them all at once it'll get hotter than a stovetop," says Gustafson.
