WIRED: I hear you're a quantum computer repair guy.
LLOYD: Yes, I am a quantum mechanic! Those darn quantum computers break all the time.
You've jumped from working on quantum computers to saying, oh, by the way, the universe is a gigantic quantum computer.
When you zap things with light to build quantum computers, you're hacking existing systems. You're hijacking the computation that's already happening in the universe, just like a hacker takes over someone else's computer.
What is the universe computing when we are not hijacking it for our own purposes?
It computes itself. It computes the flow of orange juice as you drink it, or the position of each atom in your cells.
Um, how many times have you seen The Matrix?
Sadly, only once. In The Matrix, what you see is fake - a simulation of bits - which is only a facade of what is real beneath it. But our universe is a simulation so exact that it is indistinguishable from the real thing. Our universe is one big honking quantum �mech�anical computer.
They were trying to establish exactly how organic photosynthesis approaches 95% efficiency, whereas the most sophisticated human solar cells operate at only half that. What they discovered is nothing short of remarkable. Using femtosecond lasers to follow the movement of light energy through a photosynthetic bacterial cell, Engel et al. observed the energy traveling along every possible direction at the same time. Instead of following a single trajectory like the electrons on a silicon chip, the energy in photosynthesis explores all of its options and collapses the quantum process only after the fact, retroactively “deciding” upon the most efficient pathway.
