The Human Brain may be even More Powerful to a Computer than we thought.


The brain may be more powerful than standard computers. A new study suggests that the amount of information in the brain is 10 times larger than previously estimated. 

For as fast and powerful as computers have become, they still pose no match for the human brain. Sure, a computer specifically programmed to perform singular task such as, say, playing chess can give a human a run for his or her money, but when we measure a computer against the entirety of what a human mind is capable of, it’s not really all that close.


Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies, use 25% of all the energy the body requires each day, and became enormous in hardly any time in evolution, leaving our cousins, the great apes, behind.

There are some who believe that we're just one generation away from a computer more intelligent than humans. But even if that were true, it wouldn't matter, at least in the short term, according to new research, which suggests that quantum physics may prevent quantum computers from ever reaching the full potential predicted by Moore's Law. 

In a landmark paper just published in Quantum Information Processing, researchers theorize that computers powered by the principles of quantum physics may not be able to completely liberate themselves from the physical and environmental constraints faced by classical ones. Nevertheless, they still could perform certain functions substantially better than any classical computer, such as technology-assisted human brain imaging.

For decades computer scientists have strived to build machines that can calculate faster than the human brain and store more information. The contraptions have won. The world’s most powerful supercomputer, the K from Fujitsu, computes four times faster and holds 10 times as much data. And of course, many more bits are coursing through the Internet at any moment. Yet the Internet’s servers worldwide would fill a small city, and the K sucks up enough electricity to power 10,000 homes. The incredibly efficient brain consumes less juice than a dim lightbulb and fits nicely inside our head. Biology does a lot with a little: the human genome, which grows our body and directs us through years of complex life, requires less data than a laptop operating system. Even a cat’s brain smokes the newest iPad—1,000 times more data storage and a million times quicker to act on it.
