It sounds like you already figured this out, but you can't encode classical information into the system in such a way that would allow for FTL transfer of information. Depending on what you are specifically thinking of as "encoding", there will be an equivalent reason why it won't work; often because you collapse the wave function of your local quantum pair-element when you transfer energy into it, which is a form of observation.
