Összefonódottság

Összefonódottság is a Hungarian term that translates to entanglement in English, a phenomenon in quantum mechanics. It describes a state where two or more quantum particles become linked in such a way that they share the same fate, regardless of the distance separating them. Even when separated by vast distances, measuring a property of one entangled particle instantaneously influences the corresponding property of the other particle(s). This connection is not due to any classical communication or influence; it is a fundamental aspect of quantum reality.

The concept of entanglement was first introduced by Erwin Schrödinger in 1935, building on the work of Albert Einstein, Boris Podolsky, and Nathan Rosen. Einstein famously described entanglement as "spooky action at a distance" because it seemed to violate the principle of locality, which states that an object is only directly influenced by its immediate surroundings. However, numerous experiments have since confirmed the reality of entanglement, demonstrating its robust nature.

Entanglement has profound implications for our understanding of the universe and has opened doors to new technological possibilities. It is a cornerstone of quantum computing, where entangled qubits can perform calculations far beyond the capabilities of classical computers. It also plays a crucial role in quantum cryptography, enabling secure communication through the principles of quantum mechanics. Furthermore, entanglement is a key concept in quantum teleportation, a process that allows the transfer of quantum information from one location to another. The study of összefonódottság continues to be a vibrant area of research, pushing the boundaries of our knowledge in quantum physics.
