Photon, an elementary particle of light, can teleportation over a straight-line distance of 6Km
In a first, scientists have successfully teleported a photon – particle of light – over a distance of six kilometres
Through a collaboration between the University of Calgary, The City of Calgary and researchers in the United States, a group of physicists led by Wolfgang Tittel, professor in the Department of Physics and Astronomy at the University of Calgary have successfully demonstrated teleportation of a photon (an elementary particle of light) over a straight-line distance of six kilometres using The City of Calgary's fibre optic cable infrastructure. The project began with an Urban Alliance seed grant in 2014.
A advance that may enable secure communication without having to worry about eavesdropping.
The experiment is based on the entanglement property of quantum mechanics, also known as “spooky action at a distance” – a property so mysterious that not even German physicist Albert Einstein could come to terms with it.
The research could not be possible without access to the proper technology
. One of the critical pieces of infrastructure that support quantum networking is accessible dark fibre. Dark fibre, so named because of its composition — a single optical cable with no electronics or network equipment on the alignment — doesn’t interfere with quantum technology.
The City of Calgary is building and provisioning dark fibre to enable next-generation municipal services today and for the future.
This demonstration is arguably one of the most striking manifestations of a puzzling prediction of quantum mechanics, but it also opens the path to building a future quantum internet
, the long-term goal of the Tittel group.
