Quantum entanglement is a connection between two tiny particle | Daily Science

Quantum entanglement is a connection between two tiny particles, such as atoms or subatomic particles, that can interact with each other even when they are far apart. Imagine two coins that can tell each other what side is facing up, even if they are on opposite sides of the world. This connection is instantaneous and defies the laws of classical physics. Scientists are still trying to fully understand it, but it has many potential applications in technology, such as super-secure communication and computing.
