How fast is quantum entanglement?

The fastness of quantum entanglement at the attosecond scale.

Researchers from TU Wien and China have developed computer simulations to investigate ultrafast events, allowing for the study of quantum entanglement on attosecond time scales. When two particles are quantum entangled, they cannot be described independently; their properties are interconnected. Prof. Joachim Burgdörfer from TU Wien notes that mathematically, entangled particles remain inseparable, even when separated by large distances.
