3. Entanglement matters but it's not exactly that information is transmitted instantaneously

There are correlations that change basically instantaneously but it's a well-known result in the field that you cannot use those changes to transmit information.

What quantum computing does allow is for a sort of supercharged parallelism that, for example, allows for new algorithms such that the way the computational time scales differently with the size of the computational task.

The headline is vastly over-hyped; this is a proof of principle experiment that remains quite a way off from applications. Not to say that it isn't an important step... just don't expect to use this technology anytime soon
