Im writing a script called Earth's last twilight, it's about earth using a quantum satellite array to detect an unstable star 50 light years away that will go hyper nova and grb that will hit earth. I believe quantum entanglement would allow you to read a planet, star etc chemical composition, temperature, gravitational field strength etc but if I'm wrong tell me. Basically we only have current technology other than fusion and portable quantum technology using an emulator to sim digital quality but faster. ( Had to give us something to fight back with but both techs are recently discovered and not fully intergraded yet) I'm uncertain about the issue with if it created a black hole after it exploded would earth be affected? I'm thinking the quantum tech uses a self contained ( like how batteries are) 3d printed clear plasma board layered with nano circuits and logic diamond chips and q gates with a super conductive coolant that is circulated through the circuits via a micro pump or turbine/fan type set up, it uses a type of quantum entanglement drive to communicate with other CPUs, not sure if that could be realistic for upgrading existing tech.
