crowded quantum information
it does seem that there is a faster than light signalling with quantum entanglement issues, but that it cannot transfer any signal other than the basics used to determine a static outcome. Is this because no information can be "added on" to the basic mathematics that determines what is only allowed to happen in normal nature? Could it be possible to artificially "add on" signalling by building unique entangled structures that have a greater bandwidth?
And again you are incorrect.
The so-called Schrödinger-cat experiments refer to producing quantum superpositions of mesoscopic systems (size bigger than a single elementary particle, but still not daily-life size). The results were published in 2018, it was made with microbeams of silicon 10 micrometers long and 1x0.25 micrometers across, keeping quantum coherence all along. This is the experiment:
