quantenverschränkten
Quantum entanglement, often referred to as "quantenverschränkung" in German, is a fundamental phenomenon in quantum physics where two or more particles become inextricably linked, such that the state of one particle instantaneously influences the state of the other(s), regardless of the distance separating them. This effect was first described by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935 in what is now known as the EPR paradox, where they questioned the completeness of quantum mechanics due to what they perceived as "spooky action at a distance." Later, John Stewart Bell developed mathematical inequalities to test whether quantum mechanics could truly produce such correlations, which experiments have since confirmed.
The key feature of quantum entanglement is that measuring one particle in an entangled pair (or larger
