The demonstration showed that it could one day be practical to use high-capacity, free-space quantum communication to create a highly secure link between ground-based networks and satellites, a requirement for creating a global quantum encryption network.<\/p>\n<p>Quantum encryption uses photons to encode information in the form of quantum bits. In its simplest form, known as 2D encryption, each photon encodes one bit: either a one or a zero. Scientists have shown that a single photon can encode even more information\u2014a concept known as high-dimensional quantum encryption\u2014but until now this has never been demonstrated with free-space optical communication in real-world conditions. With eight bits necessary to encode just one letter, for example, packing more information into each photon would significantly speed up data transmission.<\/p>\n<p>\u201cOur work is the first to send messages in a secure manner using high-dimensional quantum encryption in realistic city conditions, including turbulence,\u201d said research team lead, Ebrahim Karimi, University of Ottawa, Canada. \u201cThe secure, free-space communication scheme we demonstrated could potentially link Earth with satellites, securely connect places where it is too expensive to install fiber, or be used for encrypted communication with a moving object, such as an airplane.\u201d<\/p>\n<p><!-- Link: <a href=\"https:\/\/futurism.com\/high-dimensional-quantum-encryption-performed-in-real-world-city-conditions-for-first-time\/\">https:\/\/futurism.com\/high-dimensional-quantum-encryption-per...irst-time\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city.
