Quantum Communication Demonstrated in Real-Life City Conditions

A quantum-encrypted message containing

more than one bit of information in each particle of light was beamed through the air between two buildings in a real-life city for the first time, a demonstration that could simplify quantum communication and make it more viable in the future, according to a recent study.
Scientists previously demonstrated in laboratory conditions that a single particle of light, or photon, could encode multiple bits of information. But until now, the experiment had never been demonstrated in a real-world scenario.
"So far, people have done quantum communication in such a way that they can send either zero or one: one bit of information," said study lead author Ebrahim Karimi, an assistant professor in the Department of Physics at the University of Ottawa. [The 9 Most Massive Numbers In Existence]
