that 10,000 digit number December 10, 2006

Posted by Sharath Rao in science.

I am sure we all understand the question below.

Say we decide to factorise a 10,000-digit integer, the product of two very large primes. That number cannot be expressed as a product of factors by any conceivable classical computer. Even if you took all the matter in the observable universe and turned it into a computer and then ran that computer for the age of the universe, it wouldn’t come close to scratching the surface of factorising that number. But a quantum computer could factorise that easily in seconds or minutes. How can that happen?

…..and few really understand the possible solution.

For now ( and forever ) I will sit back and enjoy how mathematics and nature time and again humbles humankind….until one day man turns the tables.

As someone said :

Most scientific breakthroughs are nothing else than the discovery of the obvious.
