One year ago Hacked covered the race between the US and China to develop “military super-powers” by harnessing quantum science, and noted that Chinese scientists were developing quantum communication satellites that support unbreakable encryption. A few weeks ago, China launched its first quantum satellite.
A team of researchers from the University of Technology Sydney (UTS) have found a material capable of emitting a single pulse of quantum light at room temperature, on demand.
The team’s discovery has been published in a paper called “Quantum Emission from Hexagonal Boron Nitride Monolayers” in the journal Nature Nanotechnology and can be found here.
Room-temperature quantum emitters have, until now, only been observed in a three dimensional material such as a diamond, putting a roadblock on any plans to get photons – a particle of light, rather than electrons, to process information when using such components in modern devices that contain chips. Thin, linear materials [...]
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 [...]
