Kvantsekkumine

Kvantsekkumine, 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. When particles are entangled, measuring a property of one particle instantaneously influences the corresponding property of the other particle(s), even if they are light-years apart. This seemingly paradoxical behavior was famously described by Albert Einstein as "spooky action at a distance."

The entangled state means that the particles are described by a single quantum state, rather than individual states. For example, if two electrons are entangled in terms of their spin, and one is found to have spin up, the other will instantaneously be found to have spin down, and vice versa. This correlation is not due to any hidden variables or pre-determined states, but rather an intrinsic property of the quantum system.

Kvantsekkumine has profound implications for our understanding of reality and has paved the way for potential technological advancements. It is a fundamental concept in quantum computing, quantum cryptography, and quantum teleportation, where information can be transferred between locations without physically moving the carrier of the information. Despite its counter-intuitive nature, kvantsekkumine is a well-established and experimentally verified phenomenon.
