kvantpõimendumise

Kvantpõimendumine, often translated 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 means that 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 between the particles; rather, it is an intrinsic feature of their quantum state.

The concept of quantum entanglement was famously described by Albert Einstein, Boris Podolsky, and Nathan Rosen in their 1935 EPR paradox paper. They argued that entanglement implied "spooky action at a distance," questioning the completeness of quantum mechanics. However, subsequent experiments, particularly those based on Bell's theorem, have repeatedly confirmed the existence of entanglement and demonstrated that it violates the inequalities that classical physics would impose.

Entanglement has significant implications for our understanding of reality and is a crucial resource for emerging quantum technologies. It forms the basis for quantum computing, where entangled qubits can perform calculations that are intractable for classical computers. It is also essential for quantum communication protocols, such as quantum key distribution, which offers unparalleled security. Furthermore, entanglement plays a role in quantum teleportation, a process that transfers the quantum state of a particle from one location to another. The study of kvantpõimendumine continues to be a vibrant area of research, pushing the boundaries of both theoretical physics and technological innovation.
