For the first time, researchers have teleported 10,000 bits of per second from point A to point B across a distance of about six millimeters and inside a solid state circuit, similar to a computer chip.

The scientists, from the Swiss Federal Institute of Technology (ETH) in Zurich, report their findings in this week’s issue of Nature.

In their experiment, the team spaced three micron-sized electronic circuits on a seven-by-seven-millimeter computer chip. Two of the circuits worked as a sending mechanism, while the other served as the receiver. The scientists cooled the chip to near absolute zero and ran a current through the circuits.

At that frigid temperature and small scale, the electrons in the circuit … become linked, sharing identical quantum states, even if physically separated from one other.


Other experimenters have teleported quantum bits, too, and have done so across a larger distance. But those teams only got the teleportation to work once in a while, perhaps a few percent of the time. The ETH team was also able to teleport up to 10,000 quantum bits every second, and get it to work right consistently. That’s fast enough and accurate enough to build a useful computer. “Basically we can push a button and have this teleportation work every time,” Andreas Wallraff, Professor at the Department of and head of the study, told DNews
