Savyasanchi Ghose | Missing correlation between thermodynamic entropy and information entropy in Von-Neumann's argument

ABSTRACT : In this paper, we will examine the Von-Neumann's argument related to a quantum gas undergoing a reversible process, and we will show how there is a flaw when information entropy of the observer is neglected, this process can be modified by considering the observer as a separate system and the process in which quantum gas in undergoing reversible operation as another system , both of these systems are subsystem of a system, We will consider here the physical significance of 'entanglement entropy' as information entropy. We show how inclusion of observer as system affects the information entropy and thus the overall process which leads to irreversibility in the system which was undergoing reversible operation before.
