While there is still no concrete evidence of extraterrestrial life, that does not mean there are no aliens. Currently, a group of researchers has developed a mathematical model suggesting that aliens might possess the ability to communicate across space through quantum physics.
Aliens may possess the ability to communicate across space.
On Earth, numerous efforts are underway to make quantum communication a reality. The idea here is that quantum mechanics offers certain properties that allow for faster and more secure information transmission compared to traditional systems…
One of the significant obstacles to establishing a quantum network is its fragility and susceptibility to interference. In the latest research, such networks could traverse space without breaking apart. Theoretical physicist Arjun Berera from the University of Edinburgh in the UK states that quantum states are highly delicate, and any external disturbance can lead to their destruction.
The researchers conducted extensive calculations on the movement of X-rays in the vacuum of space to examine potential decay (the breakdown of quantum states). They determined that if photons—the particles of light—are used as quantum particles, they could be transmitted across hundreds of thousands of light-years, a distance greater than the entire Milky Way galaxy.
This is partly because the average density of matter in space is much lower than on Earth, and this “cleaner” environment means there is less likelihood of interference. Even gravitational forces are insufficient to disrupt quantum communication networks. According to the researchers, it is reasonable to establish quantum communication through photons over interstellar distances, particularly for photons in the X-ray region below the electron mass.
Of course, the idea that extraterrestrial life could use quantum networks to communicate with each other or with Earth remains speculative. However, it presents another potential sign of life that they might be able to track. The research team noted that “the potential for significant information transmission” with a quantum signal makes it appealing to any extraterrestrial intelligence. Although it may require a fully operational quantum computer to decode.
