Scientists’ Quantum Computer Perfectly Simulates Nature, Basically a Simple “Mother Box”

The Wired article begins by stating how Richard Feynman predicted a computer that would perfectly mimic nature. This wouldn’t be a close approximation like what digital computers do with mathematical shortcuts. What Feynman meant was an exact replication.

Now, finally, groups at Harvard and the University of Queensland in Brisbane, Australia, have designed and built a computer that hews closely to these specs. It is a quantum computer, as Feynman forecast. And it is the first quantum computer to simulate and calculate the behavior of a molecular, quantum system.

Quantum computing’s power stems from the curiosity that a qubit — a bit of quantum information — is not limited to holding a single discrete binary number, 1 or 0, as is the bit of standard computing. Qubits exist in a limbo of uncertainty, simultaneously 1 and 0. Until the computation is done and a detector measures the value, that very ambiguity allows greater speed and flexibility as a quantum computer searches multiple permutations at once for a final result.

That’s not even the really cool part.

“Every time you add an electron or other object to a quantum problem, the complexity of the problem doubles,” says James Whitfield, a graduate student at Harvard and second author on the paper. “The great thing,” he added, “is that every time you add a qubit to the computer, its power doubles too.” In formal language, the power of a quantum computer scales exponentially with its size (as in number of qubits) in exact step with the size of quantum problems. In fact, says his professor, Aspuru-Guzik, a computer of “only” 150 qubits or so would have more computing power than all the supercomputers in the world today, combined.

You know what that sounds like to us? A Mother Box. That’s right Mister Miracle’s favorite get out of jail free card. A tool of the New Gods and Darkseid. A thing made of “Element X” that spins Boom Tubes(your basic short-cut through the universe wormhole) at your command.

Boom Tubes, people! Science is doing its damndest to catch up to our imaginations. All we have to do is let it.

And get more kids into scientific fields, of course.

NASA Addresses 2012 Doomsayers, Attacks Insanity with Facts

Just a quick post for today. NASA has had enough of this 2012 doom nonsense and seeks to set the record straight.

Q: Does the Mayan calendar end in December 2012?
A: Just as the calendar you have on your kitchen wall does not cease to exist after December 31, the Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan long-count period but then — just as your calendar begins again on January 1 — another long-count period begins for the Mayan calendar.

More sane, rational facts can be found at: 2012: Beginning of the End or Why the World Won’t End?

Even with NASA’s valiant efforts to calm the nutters of the Internets, all we foresee is 3 more years of SyFy and History Channel milking people’s fears with Doomy Dooms of Doom programs. Don’t get us started on John Cusack’s(and many others) bank account padding role in the upcoming Emmerich flick.

Just don’t.
