I just read an article about quantum computers and it was a but confusing but interesting, it has something to do with both a 1 and 0 coexisting in the same quabit in binary code. It uses quantum physics. Anyways, the developers say they can perform calculations at extremely higher rates and multiple at once, too. Discuss! Could these be manufactured at a good cost and running temperature, or do you see a need for them?

Can you link me?

On a slightly unrelated note, someone told me that on HAL 9000's Facebook page, he puts up computer memes, and one of them was ‘I once asked a quantum computer out on a date. She said maybe.’ XD

It was actually in Time magazine, so I can't

Edit: Time magazine has an online article here, but be advised it may (I didn't see any) have bad advertisements,

Well maybe is yes OR no, so I think it would make more sense if it just said yes and no.

Apparently, the most advanced calculation done on one is 3x5=15

I do not personally see these things being marketed eventually. They are currently 10 million dollars, and even with price drops only astro-physicists and huge companies will buy them. There are like 5 sold only but that is 50 million dollars :0

Well, ENIAC cost $400,000, and don't forget about inflation, causing it to be about 5 million dollars today. I think quantum computers will be viable someday, but possibly late this century or sometime next century. Between ENIAC and now has only been 61 years.

Eh. *shrugs* I still like computer humor. XD

Definitely agreed.

This summer I may intern in a lab that works on quantum computers.

What makes them so good is that the particles act as multistate waves. This means that very few qubits can explore exponential possibilities very quickly. This also means that any interaction with the system while its computing would cause its wave function to collapse, rendering all the work it had done useless.

Because one of things they are so good at is factoring huge numbers, if anyone had a quantum computer, no encryption in the world could prevent their accessing the encrypted data.

Question, though. How do engineers keep the wave functions from collapsing? To “read” the qubits, it would require some form of interaction, thus collapsing the probability wave.

Soon there may be a multipurpose quantum computer, but that will be in a long time, and besides, it is only good with calculations, Wolfram language can do it's job. But yes, Quantum Computer are a bit like a ripple on a pond, going through every place at once, while going out.
The problem may lie in the fact that it is slower than most computers in everything but computing. Think of it like a reverse science experiment. In science you use hypothesis to experiment on objects and find out about the objects. In quantum computing you use balls or quantum bits (cubits) to gain hypothesis (mathematics)

I'm sorry Dave. I can't let you do that.
