Makes sense if you know anything about quantum physics. :)

 

Seriously.

 

I hated Quantum Mechanics....

 

The most hated science class I ever took at school. But having taken it, I do understand the concepts behind the article. It still has a long way to go before it will be "useful" though.

I never took quantum physics, I got a PC tech diploma, and a Networking associates.

I am looking into going into working for myself building custom PCs maintenance and repair, but going against the big guys is pretty much useless. I definately have to study some more. I am not dumb, but that made very little sense to me.

 

Now here's a moneymaking idea for google, a simplyfying translator that can make this next section readable to somone without a Nobel prize:

 

 

 

"The logic underlying the coherent nature of quantum information processing often deviates from intuitive reasoning, leading to surprising effects. Counterfactual computation constitutes a striking example: the potential outcome of a quantum computation can be inferred, even if the computer is not run1. Relying on similar arguments to interaction-free measurements2 (or quantum interrogation3), counterfactual computation is accomplished by putting the computer in a superposition of 'running' and 'not running' states, and then interfering the two histories. Conditional on the as-yet-unknown outcome of the computation, it is sometimes possible to counterfactually infer information about the solution. Here we demonstrate counterfactual computation, implementing Grover's search algorithm with an all-optical approach4. It was believed that the overall probability of such counterfactual inference is intrinsically limited1, 5, so that it could not perform better on average than random guesses. However, using a novel 'chained' version of the quantum Zeno effect6, we show how to boost the counterfactual inference probability to unity, thereby beating the random guessing limit. Our methods are general and apply to any physical system, as illustrated by a discussion of trapped-ion systems. Finally, we briefly show that, in certain circumstances, counterfactual computation can eliminate errors induced by decoherence."

 

Is there a quantum physics for dummies ebook available? :confused:
