Is quantum information (the inverse of quantum entropy) a physical quantity that can impact the time evolution of a quantum state?
If so, can the time arrow be a result of a physical law that says "Quantum information in a closed system can not be gained"?
Is such a law the trigger for the creation and anhillation of particles and the collapse of the Wave function ? so the Copenhagen interpretation could be replaced by an observer independent mechanism that is, a quantum information law?
Does this quantum entropy impacts our current understanding of Quantum Information and Quantum Computing ? Does the process of disentanglment from entanglement increases this entropy (in contrast to von Neumann entropy)?
These two recently published papers in the Journal Entropy address these questions
