Cover Story: Quantum physics, in its current formulation, is time-reversible. We propose a definition of quantum entropy that accounts for uncertainty in the specification of a quantum state and the probabilistic nature of its observables. This entropy increases monotonically during a time evolution of fermions in coherent states. We review some physical scenarios believed to demonstrate the reversibility of quantum physics, and we show that the entropy increases. We hypothesize that the entropy of a closed system never decreases, i.e., that randomness cannot be reduced, thus inducing a time arrow in quantum physics. We also suggest that creations and annihilations of particles are triggered to bar the entropy from decreasing. View this paper
