Emaranhamentos

Emaranhamentos, often translated as 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. This connection means that the quantum state of each particle cannot be described independently of the state of the others, even when they are physically separated.

When particles are entangled, measuring a property of one 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 instantaneously be found to have spin down, and vice versa. This effect appears to violate the principle of locality, which states that an object is influenced only by its immediate surroundings, and that information cannot travel faster than the speed of light.

Albert Einstein famously referred to entanglement as "spooky action at a distance." Despite its counterintuitive nature, entanglement has been experimentally verified numerous times and is a fundamental aspect of quantum theory. It has significant implications for quantum computing, quantum cryptography, and quantum teleportation, where it is a crucial resource for these emerging technologies. Understanding and harnessing entanglement is a key area of research in modern physics.
