Researchers in China have got the first landmark that would see the development of the quantum internet worldwide by a beam of the entangled particles using the light from a satellite that is miles far apart. The scientists have just attained the first entangled photons on a satellite that orbits more than 300 miles on top of the Earth. The particles are then beamed back to the planet to two ground-based laboratories that are more than 750 miles apart.
The discovery could lead to a new form of internet that will connect the subatomic particles together regardless of the distance between them and even more, the difference between the space and the Earth.
Scientists believe that the linked particles can encrypt data and send it from one place to the other through a quantum network without the information being decrypted and exposed to others as it happens with the current internet network. The study is being conducted by Jian-Wei Pan at the University of Science and Technology, China.
According to Pan, the idea of quantum entanglement started back in 2003 when many people opposed his proposal saying it would not be possible to achieve the stated results. The initiative challenges the earlier thoughts that the world has had about the distance between the space and the Earth. The distance could be very small if space is elevated onto the quantum level.
The new experiment is the ongoing work that started in the first quantum-spacecraft satellite called Micius. The satellite creates a pair of photons that are then linked by the quantum entanglement. The photons were then beamed to the ground stations located in Nanshan, Delighha, and Lijiang. Each single particle travels more than 1,240 miles to their respective destinations.
According to Pan, the knowledge behind the cryptography that is used currently to keep the data safe in the world today depends on the complex mathematical formulas that can be hacked easily by cyber criminals and hackers. The quantum network that is still under study could enhance the security of data thus benefitting the human race.
