Quantum entanglement speed is measured for the first time, and it's too fast to comprehend

This news article explains how scientists have measured the speed of quantum entanglement for the first time using attoseconds. The research team, led by Prof. Joachim Burgdörfer from TU Wien, used advanced computer simulations and laser experiments to observe the process on attosecond timescales. The findings could have significant implications for quantum technologies such as cryptography and computing.
