Scientists have used quantum teleportation to send a photon from Earth to China’s Micius satellite, 500km above ground.
Editor’s Remarks: Beam me up, Scotty! The Micius satellite was launched into space last year and was designed specifically for quantum experiments. The scientists have created a ground-to-satellite quantum network and used a process called “entanglement” to recreate the exact properties of one photon on Earth into another one in space. Same photon but different location – the “entangled” photons exist in a shared state and an action on one affects the other. This technique has been used in laboratories for many years, but this is the first time that it has teleported over such a long distance, and the Chinese scientists see this as a crucial step towards the creation of a global scale quantum internet. China again is taking the lead with groundbreaking new technology.
