Quantum Teleportation is Now a Reality
Alice ‘A’ is located in Manchester, Bob ‘B’ at the University of Calgary and Charlie ‘C’ in a building next to City Hall in Calgary downtown. The teleportation distance—in our case the distance between Charlie and Bob—is 6.2 km. All fibres belong to the Calgary telecommunication network but, during the experiment, they only carry signals created by Alice, Bob or Charlie and were otherwise ‘dark’.

It is possible to transfer information by using quantum mechanics over thousands of miles.

Scientists have successfully transferred quantum information from one network to another over several miles. The quantum information was transferred through commercial optical fiber networks.

This means a breakthrough for quantum teleportation. The transfer was carried out from Calgary, Canada all the way over to Hefei, China. The experiment has been described in detail in two different studies by the two sets of scientists published in the journal Nature Photonics.

You may be wondering why is this development being hailed as a breakthrough? Let us tell you the phenomenon of quantum transport was first proposed by scientist nearly two decades ago.

But some deemed it to be impossible. Quantum teleportation takes place with the help of ‘Entanglement’ which is a weird process in which two subatomic particles, entangle with each other and simultaneously change the state of one another.

Albert Einstein once described the phenomenon as “spooky action at a distance”. But it seems quantum teleportation is not just a theory reserved for science fiction but a stuff of reality.

In the current experiment researchers sent quantum information over a distance of 6.2 kilometers also equal to 3.9 miles in Calgary. While the researchers in China sent quantum information over a distance of 12.5 kilometers equal to 7.8 miles.

Although greater distances have been crossed in laboratory settings but those were carried out with new technology. This new development saw quantum travel with the help of preexisting and widespread technology.

This not only ensures the process is viable but also makes quantum travel a practical process.

Before you get too excited let us tell you ‘teleportation’ in this case is only for transfer of information and not matter. So transporting physical matter from one place to another through quantum mechanics is still a dream.
