Entanglement is one of the most peculiar aspects of quantum mechanics. It's one of the core principles that sets quantum computing apart from classical computing. This principle allows quantum computers to process a lot more information much faster, enabling them to solve certain types of problems that would be extraordinarily difficult, if not impossible, for a classical computer.
At a fundamental level, quantum entanglement is what happens when two or more particles become linked, and the state of one particle instantly influences the state of the other, regardless of the distance between them. It's important to note that entanglement is an instantaneous process, happening faster than the speed of light, which makes it a very powerful tool for quantum computing.
Let's look at some of the properties of quantum entanglement:
In quantum entanglement, the entangled particles remain connected so that the actions performed on one particle also affects the other, no matter how far they are separated. The term 'spooky action at a distance' was coined by Einstein to describe this peculiar phenomenon.
The change is state of one particle affects the state of its entangled pair instantly, faster than the speed of light.

Entanglement is not only a fascinating phenomenon but also a powerful resource in quantum information processing. It's a crucial component of many quantum computing algorithms and protocols, such as superdense coding, quantum teleportation, and quantum cryptography.
Despite the counterintuitive nature of entanglement, it proves to be a game-changer in quantum computing, putting it leaps and bounds ahead of classical computing in terms of speed and computational power.
