Beam Them Up, Scotty: Chinese Physicists Reportedly Break Teleportation Record [View all]
Source: Time
Harry Potter and Star Trek fans, rejoice! Teleportation is real. Using powerful lasers and optics to manipulate photons, or units of light, researchers in China set a record for teleporting a photon more than 10 miles, TIME reported in 2010. Now, a different team of physicists at the University of Science and Technology of China in Shanghai say they have shattered that record, claiming to have sent a photon more than 60 miles.
Quantum teleportation, which has been around since 1997, is a little different than what you see in sci-fi movies. Considered “one of the holy grails of practical quantum communication,” as the scientists write in their abstract, teleportation is the ability to essentially move one object from one place to another without traversing the space in between. But, as Forbes explains, the actual object is not moving from point A to point B. Rather, the distant photon mirrors the information contained by the original photon, essentially becoming an identical twin.
The team’s greatest contribution is not necessarily the distance they’ve made that data travel, but the method it used to harness the 1.3-watt laser beam that carries it. The longer a beam of light travels, the more it spreads out, causing the photon to lose information and trail off course. To keep the beam on target, the researchers created a technique that focuses and steers the laser. Though beaming up humans and animals à la Star Trek is not on the agenda anytime soon, as the technology becomes more sophisticated, it will likely be applied to military communication.
