A bstract Motivated by the quantum process of black hole evaporation and its implications for symmetries, we consider a qubit system with random dynamics as toy model hole. We compute symmetry-resolved entropies discuss implications. first case where charges are conserved entropies. derive analogue Page curve. then symmetry is explicitly broken no longer conserved. It serves global breaking in ...
