Sammanflätningstillstånd

Sammanflätningstillstånd refers to a quantum mechanical phenomenon where two or more particles become linked in such a way that their fates are intertwined, regardless of the distance separating them. This linkage is established when particles interact and their quantum states become dependent on each other.

Once particles are in a state of sammanflätning, measuring a property of one particle instantaneously influences the corresponding property of the other particle(s). For instance, if two electrons are sammanflätade in terms of their spin, measuring the spin of one electron to be "up" will instantly determine that the spin of the other electron is "down," even if they are light-years apart. This correlation is stronger than what classical physics can explain.

The term "sammanflätning" translates to entanglement in English. This non-local correlation is a fundamental aspect of quantum mechanics and has significant implications for fields like quantum computing and quantum cryptography. Albert Einstein famously described this phenomenon as "spooky action at a distance." Despite its counter-intuitive nature, sammanflätningstillstånd has been experimentally verified numerous times.
