The von Neumann Entropy: A Reply to Shenker (2003)

unapi

Shenker has claimed that Von Neumann's argument for identifying the quantum mechanical entropy with the Von Neumann entropy, S([rgr]) = - ktr([rgr] log [rgr]), is invalid. Her claim rests on a misunderstanding of the idea of a quantum mechanical pure state. I demonstrate this, and provide a further explanation of Von Neumann's argument.
