A treble quantum system is a complex case, I have worked on such system but still I need more opinions and I want to share my acknowledgments with any interesting researchers to strength our back grounds in this field.
I think that a single quantum system is enough. You need to talk to Eric Verlinde. He is promoting information in primordial Qbits as the thing that got entangled and caused the universe and everything. It is a pity he had to put acceleration in by hand though.
