'Immediately teleport' photons into space

Instant teleport - or teleport is a form of movement over time and space, taking only a few seconds to cross the distance of thousands of kilometers.

1. 4 cosmic phenomena have the speed of traveling through the speed of light
2. Timeless and mysterious disappearances break all physical laws in the mountains of Untersberg
3. Scientists confirm: People can go through, travel time

This form of instantaneous movement seems to be only in stories, sci-fi films, but it starts to gradually come true. Chinese scientists have successfully shifted one thing to the outer space satellite, with a distance of up to 500,000 meters.

A photon has been successfully transferred by Chinese experts to the Micius satellite, which has a high sensitivity function, allowing the quantum state of individual photons to be detected to serve. for human quantum experiments.

This is the first time in history that experiments have resulted in teleportation. Previously, teleportation experiments had a very limited distance, only about 100km, because the photon was . missing during the teleportation process.

What is teleportation - teleport?

In sci-fi films, humans or spacecraft move the crew with a light.

But unlike quantum physics, instantaneous displacement depends on "quantum entanglement" - a situation where a group of quantum objects (such as photons) form at the same time. and points in space. That means they share their existence with each other, and that relationship will continue no matter how far the distance between them is.

Scientists used that connection to transfer quantum information, and "download" information about the second photon. Then, this photon will have the same format and information as the first photon, and that is the "teleport" in quantum.

Chinese experts have created quantum entanglements with frequencies of up to 4,000 per second. They launch a photon onto the Micius satellite and keep a particle behind. Finally, they create a state of entanglement with distances of up to 500km.

This entanglement is quite fragile and fragile, so it cannot transport anything larger than photons. However, this is still a major turning point in the instant teleportation technology that people dream of.
