Chinese and Canadian scientists recently announced that they have successfully carried out a form of quantum teleportation by teleporting tiny photon particles across a whole city, according to a report from the South China Morning Post.
According to the report, the two separate teams were able to teleport the photons through cables across several kilometres of optical fibre network in Calgary in Canada and Hefei in Anhui province. Even though experiments such as this have been undertaken before, this is the first time it has successfully worked in two separate laboratories.
This is believed to be a significant step forward in the creation of a quantum Internet, which [...]
Scientists at Boulder’s National Institute of Standards and Technology published a paper in the scientific journal Optica this week describing how they had recently been able to “perform highly efficient multifold coincidence measurements, resulting in the successful quantum teleportation over 100 km of fiber.”
According to some publications, such as the Christian Science Monitor, this amounts to “breaking the quantum teleportation record.” In a sense, this claim rings true – the previous record using a similar technique was 25 kilometers. However, the researchers are not talking about teleportation in the sense that most readers will think of it. They are not talking [...]
