This peculiar connection method is… quantum entanglement.
The phenomenon of quantum entanglement was discovered as early as the Earth era.
It is a 'ghostly' connection that exists between microscopic particles.
When the state of one particle in an entangled pair is determined, the state of the other particle can also be determined. This process is instantaneous, regardless of the connection between the two particles.
To make a rough, not entirely accurate analogy, it's like having one red ball and one green ball in a pocket.
Two people each take a ball from the pocket but don't know what color ball they have.
Afterward, these two people travel to different planets, for example, one goes to Mars, and the other stays on Earth.
There is then a minimum distance of 40 million kilometers between them. Based on conventional electromagnetic wave communication, the one-way communication delay would be about 133 seconds.
