Teleportation is the transfer of an object from one point in the universe to another without travelling through the space in between. It is common practice in many labs around the world. Since the early 90s, physicists have used it to teleport increasingly complex objects starting with photons and more recently with atoms and ions.
But that’s just the beginning. Back in 2010, we looked at the extraordinary work of Masahiro Hotta at Tohoku University in Japan who has worked out that it ought to be possible to teleport energy too. That’s something that could have profound implications for the way quantum devices and machines might be made to work in future.
But energy teleportation has an important limitation–the distance over which it can be sent. The limitations are so severe that it’s hard to see how energy teleportation could help even at the nanoscale. This “strong distance limitation has hampered experimental verification,” says Hotta.
But now he and a couple of mates say they’ve discovered a way round this limitation that allows energy to be teleported over almost any distance. And this new protocol for energy teleportation should allow experimental verification for the first time.
