What is entanglement in quantum computing?

Entanglement in quantum computing refers to a phenomenon where two or more quantum particles become correlated in such a way that the state of one particle cannot be described independently of the state of the other particles, regardless of the distance between them. This means that the measurement or manipulation of one particle instantaneously affects the state of the other particles, even if they are physically separated. Entanglement is a fundamental property of quantum mechanics and is crucial for various quantum computing algorithms and protocols.
