【摘要】 The conflict between the dynamics postulate(unitary evolution) and the measurement postulate(wavepacket collapse) of quantum mechanics has been reconciled by Zurek from an information transfer perspective [Phys.Rev. A 76(2007) 052110], and has further been extended to a more general scenario [Phys. Rev. A 87(2013) 052111].In this paper, we reconsider Zurek’s new derivation by using weak repeatability postulate or covariant condition instead of repeatability postulate.
