My brain got this before I even read the story

I wanted to make note of a very interesting qbit of news from the Quantum realm that I stumbled across today:

Quantum computing without computing

I'm still trying to fully comprehend this - without running the algorithm, you can determine it's results due to quantum mechanics (counterfactual computation). If I understand this correctly, basically you cna eliminate all of the values that cannot be the answer beore running the algorithm, which leaves you with only those values that *can* be the answer.

My favourite quote from the article:

In a sense, it is the possibility that the algorithm could run which prevents the algorithm from running -- Paul Kwiat
