Teleportation has long been the dream of science fiction enthusiasts. And although there have been no advances in human teleportation, there have been significant strides in advancing the teleportation of information. Recently, physicists at ETH Zurich succeeded in teleporting information from one point to another on an electronic chip. This might not seem like a big deal, as information transfers on computer chips are not exactly a new concept, but this is the first time that quantum physics has been used to make the information disappear from one point of an electronic circuit and then reappear at another.
On a standard computer chip, information is transferred with moving electrons. However, ETH designed their electronic circuit to handle information by using quantum physics. The information is transported by creating a quantum state between two corners of the chip. This means that the particles containing the information interact with each other, but then become separated. After separation, the particles are still entangled on a quantum level, allowing them to teleport. So, instead of having information travel between two points, it actually disappears from one and reappears at another.
In this experiment, the information teleported across six millimenters, from one corner of the circuit to another. This is small in comparison to previous experiments that used visible light for teleportation. However, the ETH physicists were the first to use electronic circuits and created a system that teleported around 10,000 quantum bits per second.
The next step in this research will be experimenting with teleporting information from one electronic circuit to a completely different one. Increasing the teleportation distance in this manner could change the future of quantum computing: this system allows for a greater amount of information to be stored and transported than with traditional computing.
