Quantum computers

Quantum computing breakthrough arises from unknown molecule

I found this really interesting. You'd think that this would make every computer job obsolete when they get it going.

[Chaos Clown]

Wow, that is interesting. Especially the two computers communicating across solar systems. Also, if you could afford it, the games that you could run on those things would be amazing. Now I feel a strange urge to find out exactly how these things work...

What if you could send a certain type of information to somebody's quantum computer which would cause it's processor to turn into an atom bomb? (lol I know nothing about quantum physics)

then they would get a hell of a surprise when they hit the power button?

The interesting part of quantum physics is that most (if not all, I'm no quantum physicist) of these particles come in pairs. Changing one's charge (or rotation or something? unsure) changes the other -- no matter how far apart they are. Also I didn't RTA.

Does this change occur instantaneously or at the speed of light? If instantaneously, I could envision an information time machine. One computer and particle remains stationary while the other is sped away very fast. The particles acts as the information gateway. The stationary computer and particle should age more quickly than the other. See where I going with this?

I don't know much about physics either, but I would guess that for a quantum computer, the processor would need to be made of a material that can sustain a chain reaction at the atomic level for nuclear fission or fusion; namely uranium or something alike.

[Chaos Clown]

Unfortunately, quantum != radioactive. Sorry, no tiny exploding processors for you.

[MarauderIIC]

Sorry, I don't know. I just pulled that little bit out of memory.

I'm a bit afraid what will happen when a cracker gets hold of a quantum computer and decides to start brute forcing financial institutions. A computer that can calculate all data at once? Scary.

once its possible to make quantum computers websites of these kinds will most likely change to accustom thanks to prior knowledge that will be given to them no doubt

One of my proffessors was a quantom physisist he worked at cal tech and nasa. I still dont know why he chose to become a university proffesor. But today another one of my proffessors was telling me about quantom computers he said that the longest distance of 2 computer parts connecting instantly was 15 miles bugt he says he knows that they have gone over 30 miles bfore (he also worked at cal tech) He says this will be useful for flying airplanes in battle since the piot doesnt actually die. If you use radio waves there is a delay so the person in the unmanned plane will always have a disadvantage. which is why so much funding is going into quantom science.

Oh and another cool thing is quantum computers don't have to operate in base 2 (no wires so that means they can function in base 3 and higher) that means that whenever these things go public we wont be dealing with 0's and 1's we will be dealing with a, b, c, and aybe even higher. My professor says that they already have computers that run fine in higher bases.
