The tension between unitarity and wave-packet collapse is an annoying problem in quantum mechanics, while a breakthrough was made by Zurek recently from the point of view of information transfer. In this paper, we reconsider Zurek's derivation in the setting of generalized probabilistic theories (GPT), and establish that actionable information about a system can be repeatedly passed on to other systems only when the chosen states of the system have mutual zero fidelity. This may be interpreted as an extension of Zurek's result to GPT.

... The later seeks an explanation of the apparent transition from the quantum realm to the classical realm (i.e., the emergence of a classical objective reality from the quantum substrate) as described by quantum Darwinism [20][21][22][23][24][25][26][27][28][29][30]. Decoherence serves as a natural arena for the interplay among wave-particle duality [31][32][33][34][35][36], wave-packet collapse [8,9,37,38], information transferring [39][40][41], state broadcasting [42][43][44][45][46][47], and quantum correlations (quantum discord) [48][49][50][51][52][53][54]. Decoherence is also employed in the theory of decoherent histories (consistent histories) approach to quantum mechanics [55][56][57][58][59]. ...
