Kvanttilinkit

Kvanttilinkit, often translated as quantum entanglement, is a phenomenon in quantum mechanics where two or more quantum particles become linked in such a way that they share the same fate, regardless of the distance separating them. This means that the quantum state of each particle cannot be described independently of the state of the others, even when separated by a large distance.

When particles are entangled, measuring a property of one particle instantaneously influences the corresponding property of the other particle(s). For example, if two electrons are entangled in terms of their spin, and one is measured to have spin up, the other will instantaneously be found to have spin down, and vice versa, no matter how far apart they are. This apparent instantaneous correlation led Albert Einstein to famously describe entanglement as "spooky action at a distance."

Entanglement is a fundamental concept in quantum physics and has significant implications for quantum computing, quantum communication, and quantum cryptography. It is a key resource that allows for the development of technologies that are impossible with classical physics. While the mechanism of this correlation is not fully understood in a classical sense, it has been experimentally verified numerous times and is a cornerstone of our understanding of the quantum world. The principle has been demonstrated with photons, electrons, and even larger molecules.
