My understanding is that it can solve only a limited number of math. problems, but faster than the conventional computer.

D-Wave Two processor was designed specifically to perform a process called "quantum annealing", which is a technique for finding the global minimum of a complicated mathematical function.Miss Natalia your understanding is up-to mark . I am in total agreement with your statement .

# Mohammed Sir , yes even David Deutch isn't able to claim anything bout Quantum Computer .But lets hope we get something in near future , simply as  Sir Marković G. Đoko said it will be revolution really ! . I perceive that we will have to leave out classical computers. Since the current age is becoming age of Voluminous Data !!  

I found this little simulator on the website of university of bristol , its interesting to use .

Wait a minute. What did a presenter showed to us at the Caltech IQIM talk?  A photo of  D-Wave Two quantum computer. Looked pretty big to people who got used to Mac Book Air.

Yes Dwave is as big as the classical computers were before many years ! takes lot of space.

I remember it takes the whole room. And it is good to solve efficiently complex optimization problems. Actually, the history of quantum computing began  at Caltech in 1994, when one very talented postdoc wrote a code for factorization on a hypothetical qc.

yes exactly , And the post doc would have been none other than Peter Shor !! 

His algorithm if a quantum computer is realised , will endanger all types of RSA governed securities what we call " Bank Level Security" .Which means none of the password will be secure !! Interesting isnt it ! 

I get a notion that Quantum world is in its infancy but lot of research is going on in this feild and I am also trying to do post Doc in this very feild but not finding anything till now, because of its interesting nature and the challenge it is . 

For me it is very strange that no one has come with a  very simple "KING ARTHUR'S SWORD" benchmark case. If D-wave's computer is indeed special it would remove the sword from the stone. Otherwise it would simply be a failed computer or... even a fraud. It would not be, for sure, the first fraud in the history of science... Of course, I hope that this computer can do his job well:)
