Teleportation

Prof. Guangcan Guo’s team from CAS and USTC published an in-depth review on quantum teleportation, highlighting its importance in quantum communication and computing. The team’s advancements include creating a high-fidelity 32-dimensional quantum entanglement and its successful transmission over long distances, with the paper also discussing quantum technology’s future practical development.A team led by Academician Prof. Guangcan Guo from the Chinese Academy of Sciences (CAS) provides a comprehensive overview of the…

By David L. Chandler, Massachusetts Institute of Technology June 25, 2023MIT researchers have discovered that novel photovoltaic nanoparticles can emit streams of identical photons, potentially paving the way for new quantum computing technologies and quantum teleportation devices.The device emits a stream of single photons and could provide a basis for optical quantum computers.Using novel materials that have been widely studied as potential new solar photovoltaics, researchers at <span class="glossaryLink"…

Scientists in the Netherlands have made a major step towards quantum computer networks by teleporting quantum information between two nodes that didn’t have a direct link to each other. The breakthrough heralds a faster and more secure communication system.As the name suggests, quantum computers tap into several principles of quantum mechanics to perform calculations that are beyond the reach of traditional computers. And just like our current internet, these quantum computers will need to be linked together to achieve…

As you approach the orbit of your new home planet, Gliese 667CC (opens in new tab), you realize you made a terrible, terrible mistake: you didn’t download the latest firmware update for your ships’ communication protocols. While this would be a secondary concern around Earth’s orbit, where the servers holding the installable package reside and radio communications are speedy enough (opens in new tab) to make do, things are different when you’re 22 light-years away from humanity’s cradle. There’s no way for you to…
