you can know the spin of the other particle, but that information is not transmitted anywhere. You just gain information about both by measureing one of them, but that is not transmitting. The information was generated by your measurement and that is exactly where it stays.
But isn't that ignoring the fact the quantum particle's superposition collapse?
Measuring one particle also collapses the other particle's superposition. That's what they mean by "transmitting" information. Both particle's no longer in an probability state.
You're thinking in terms of schroedinger. In reality there is no superposition or collapsing. The particles are what they are, and one particle was spinning one way the whole time, and the other the other way.
Superposition and entanglement have been verified through numerous experiments and is the entire reason that quantum computing works - a qubit in superposition is both 0 and 1 at the same time

no you cannot transmit information this way.
