Call it the quantum Garden of Eden. Fifty or so miles east of New York City, on the campus of Brookhaven National Laboratory, Eden Figueroa is one of the world’s pioneering gardeners planting the seeds of a quantum internet. Capable of sending enormous amounts of data over vast distances, it would work not just faster than the current internet but faster than the speed of light — instantaneously, in fact, like the teleportation of Mr. Spock and Captain Kirk in Star Trek.

Sitting in Brookhaven’s light-filled cafeteria, his shoulder-length black hair fighting to free itself from the clutches of a ponytail, Figueroa — a Mexico native who is an associate professor at Stony Brook University — tries to explain how it will work. He grabs hold of two plastic coffee cup lids, a saltshaker, a pepper shaker and a small cup of water, and begins moving them around on the lunch table like a magician with cards.

“I’m going to have a detector here and a detector here,” he says, pointing to the two lids. “Now there are many possibilities. Either those two go in here” — he points to the saltshaker — “or the two go in there,” nodding at the cup of water. “And then depending on what happened there, that will be the state,” he says, holding up the black pepper shaker, “that I’m preparing here.”
