Quantum entanglement can instantaneously transmit quantum information, namely the quantum states of the entangled particles, but it can’t instantaneously transmit classical information. So, in these experiments, there has to be an conventional channel for transmitting additional bits of classical information at subluminal speeds, in order to complete the teleportation process. This is probably just another example of “science writers” not really understanding science.
But can’t those quantum states themselves BE that information?
