Entanglement theory, also known as quantum entanglement, is the phenomenon where particles become connected in a way that transcends classical notions of space and time.
Imagine two particles, A and B, created from a single source. Measuring the state of particle A will instantly affect the state of particle B, regardless of distance.
This is because the act of measurement itself is what causes the entanglement, rather than any physical connection between the particles.
The implications of entanglement are profound: it suggests that information can be transmitted instantaneously across vast distances, defying the speed limit imposed by space and time.
