New records bring super-powerful quantum computers closer to reality

In what are claimed to be new world records, two teams working in parallel at the University of New South Wales (UNSW) in Australia have each found solutions to problems facing the advancement of silicon quantum computers. The first involves processing quantum data with an accuracy above 99 percent, while the second is the ability to store coherent quantum information for more than thirty seconds. Both of these records represent milestones in the eventual realization of super-powerful quantum computers.

Each of the teams produced two types of quantum bits (the vertical and horizontal polarization of an electron representing the binary state of 1 and 0 – known as qubits) in their research. One qubit, developed by the team led by Professor Andrew Dzurak, using an "artificial atom" produced in a MOSFET (Metal oxide semiconductor field effect transistor), and the other, developed by the team led by Associate Professor Andrea Morello, used a "natural" phosphorus atom to develop their qubit.

In both cases, keeping qubits in their fragile quantum states long enough to use them to store information and accurately read the results whilst ensuring that tiny error rates don’t quickly add up when millions of computations are performed, are integral factors in creating future quantum computers and the accuracy of the quantum algorithms that will drive them.

i just posted some stuff because theres a bunch of stuff

You can buy one if you want.

There's a lot of controversy about the d wave though, most likely it isn't a "true" quantum computer (although it is very fast at certain types of computations)

the video games with those computer would be nuts

hate to disappoint but quantum computers are just good at doing certain types of problems

like the ones involved in cryptography and encryption ( http://en.wikipedia.org/wiki/Integer_factorization ). with a quantum computer you could break basically any of the encryption algorithms used today. meaning i could finally crack the dsf admin password and ban jaydot

With what's been going on with fiber optics, physics and such things are getting closer. We can only fit so much nano or mini on a processor without compensating.

The thing about quantum physics is it's always the Schrodinger cat argument (at basic level, though we've gotten further in older layman terms in audio compared to gribbon's intro to quantum), the closer we get closer questions like that will no longer be quantum physics like the problem of dark matter as a stand in for we don't get it with astrophysics.

your post is a bit unintelligible but if im interpreting it right:

things like bell's theorem are basically overwhelming evidence that quantum mechanics isn't just "oh we don't understand it yet," but rather that, whether we like it or not, quantum phenomena like uncertainty, superposition, entanglement, etc are just the way the universe works. (also schroedingers cat is supposed to be absurd: it was made to point out that the copenhagen interpretation of QM doesn't make sense because it implies a cat could be dead or alive at the same time. other QM interpretations don't have the same problem)

also dark matter isn't really a "stand in for what we don't get with astrophysics." it's very obvious that it isn't an astrophysics problem - that implies that it's just a matter of figuring out some unknown phenomenon to explain the discrepancies in galaxy rotation curves, the shape of the bullet cluster, etc. the only proposed cosmological / astrophysics solution is a borderline crackpot theory. we know that the problem is that dark matter is composed of some as of yet unknown type(s) of particle(s), which is a field theory / particle physics problem.

Bring back the Pilot Wave conjecture I say!

Honestly it's a shame that the Copenhagen interpretation is the default that everyone clings to, I've always felt the way that it treats observation / measurement is a bit of a cop out

im about to get my ass kicked by this electromagnetism exam
