Quantum Computers

[perplex]

I've read little info in magazines about the theory of quantum computing, but do any actually exist in labs? i know not for Personal Computers but for mathematical calculations like a supercomputer, a prototype?

I believe IBM has successfully implemented shor's algorithm to factor 15 into 3 and 5 using however many qubits that requires. I don't have sources to cite for this sadly. The problem is that a lot of the math hasn't been publically announced, and a lot of the big companies have patents on a lot of the tech (IBM is a major player in quantum tech). Currently its pretty much research only except for quantum encryption, which some banks in Europe have taken advantage of.

I have a source for that, Wikipedia :

See the Nature article in the references below reporting on work at IBM Almaden Research Center, where scientists implemented a seven qubit computing device that ran Shor's factorization algorithm.

OK thanks, maybe by 2050 we'll see something
