Quantum entanglement. Sounds like a pretty complicated concept, right? It turns out that the basics of quantum entanglement can be explained with three simple concepts.

The first is the concept of superposition. In layman’s terms, superposition is the existence of two of the same object but in different states – for example, two electrons with opposite spins.

The second concept is that being in a state of entanglement means two objects are connected so that they communicate with each other in a way that a certain outcome is guaranteed to happen for either of them, despite the distance between them.

Lastly, the third concept is that of probability. In order to understand quantum entanglement, we must understand that the probability of any two objects having certain outcomes that coincide with each other can be extremely low, especially on a quantum level, but in the world of quantum entanglement, that probability becomes almost certain.

If we put each of these three concepts together, we can understand quantum entanglement: If two objects exist in superposition with each other, having opposite but equally likely outcomes, they can become entangled, or connected to each other, in a quantum state so that having opposite outcomes increases, if not certifies, the probability of having opposite quantum outcomes.
