'Electrons moving through a leaf or a green sulfur bacterial bloom are effectively performing a quantum “random walk”—a sort of primitive quantum computation—to seek out the optimum transmission route for the solar energy they carry. “We have shown that this quantum random-walk stuff really exists,” Fleming says. “Have we absolutely demonstrated that it improves the efficiency? Not yet. But that’s our conjecture. And a lot of people agree with it.”' This the last paragraph in the article, which has the title "Is Quantum Mechanics Controlling Your Thoughts?". The fact that this isn't the first paragraph, beneath the headline "Scientist speculates adaptive quantum computation effect in bacterial photosynthesis" makes this a shining example of what's wrong with science journalism, and why everyone should stop reading it.
