The Wired article<\/a> 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. <\/p>\n

\"\"<\/a> 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<\/a>. And it is the first quantum computer to simulate and calculate the behavior of a molecular, quantum system.<\/p>\n

Quantum computing\u00e2\u20ac\u2122s power stems from the curiosity that a qubit <\/a>\u00e2\u20ac\u201d a bit of quantum information \u00e2\u20ac\u201d 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.<\/p><\/blockquote>\n

That’s not even the really cool part.<\/p>\n

\u00e2\u20ac\u0153Every time you add an electron or other object to a quantum problem, the complexity of the problem doubles,\u00e2\u20ac\u009d says James Whitfield, a graduate student at Harvard and second author on the paper. \u00e2\u20ac\u0153The great thing,\u00e2\u20ac\u009d he added, \u00e2\u20ac\u0153is that every time you add a qubit to the computer, its power doubles too.\u00e2\u20ac\u009d<\/a> 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 \u00e2\u20ac\u0153only\u00e2\u20ac\u009d 150 qubits or so would have more computing power than all the supercomputers in the world today, combined.<\/p><\/blockquote>\n

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

Boom Tubes<\/a>, people! Science is doing its damndest to catch up to our imaginations. All we have to do is let it.<\/p>\n

And get more kids into scientific fields, of course.<\/p>\n

Just give us time, Mister Miracle.<\/a><\/div>\n
