 This work determines speed limits on informational measures such as von Neumann entropy, maximal information, and coherence for quantum systems evolving under dynamical processes, which ascertain fundamental limitations on evolution time required by the quantum systems for changes in their informational measures. The speed limit on maximal information is used to obtain minimum time required to erase quantum information via some quantum processes of interest.
