No Hacking Matter

B.C. firm to show off quantum computer:

A Vancouver-area company is set to publicly demonstrate its new quantum computer next week in what may be the first time the paradigm-shifting technology leaves the research laboratory.
Quantum technology could revolutionize the computer industry by allowing systems to simultaneously perform multiple calculations where traditional computers would have to perform them one at a time.

This is astounding if they pull it off. Quantum computing will revolutionize the computer industry, along with all its related technologies: cryptography, numerical analysis, etc.

I have my doubts that the technology will ever be publicly available: hacking will get a lot easier because of it.

  1. I think it’s very cool—if it actually works out—but I don’t think hacking will get easier in the general case. You could have all the computing power in the world trying to hack any given box and you still have to go through the same connection space. Like defending a narrow doorway, even one guy can hold off all the world’s armies pretty well; especially since, in the computer world, that man can close the door at any moment. Speaking of which: 300.

  2. The time to hack is dependant on processing power, not by bandwidth. Based on a public key and the resulting cypher in order to get the message out of if you have to try all combinations of characters, and when your processed cypher matches the original processed cypher you have the message. To get that processed cypher is what takes a long, long time to get. The more characters then the exponentially longer it takes to get the message because there’s exponentially more combinations to guess (like if you compare winning 6/49 to super 7, it’s exponentially easier to win the 6/49, but it still ain’t easy).

    If you can check 500 different combinations in a second on a normal computer, and say it takes 10 minutes to decrypt (at a total 300000 “guesses”) to get to the result. If you could check 64000 every second it would take 4.7 seconds to get the result.

    Of course, mr. jody will tell me I’m wrong about the encryption theory. My assumptions are obviously ludicrus (500 checks a second is probably way low). I’m just trying to show scale. It brings the “omg 512bit encryption is totally unhackable!!” down to “sure, I’ll own all your banking information by tomorrow”.
