Kvanttisaarron

Kvanttisaarron, known in English as quantum entanglement, is a phenomenon in quantum mechanics where two or more particles become linked in such a way that they share the same fate, regardless of the distance separating them. This connection is established when particles interact in a specific manner, often originating from a common source. Once entangled, the quantum state of each particle cannot be described independently of the others, even when separated by vast distances.

Measuring a property of one entangled 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 instantly be found to have spin down, or vice versa, depending on the initial entangled state. This seemingly instantaneous correlation puzzled Albert Einstein, who famously referred to it as "spooky action at a distance."

Despite its counterintuitive nature, quantum entanglement has been experimentally verified numerous times. It is a fundamental aspect of quantum mechanics and has significant implications for various fields, including quantum computing, quantum cryptography, and quantum teleportation. Researchers are actively exploring ways to harness and control entanglement for technological advancements. The phenomenon highlights the non-local nature of quantum reality and challenges classical notions of causality and locality.
