Shenker has claimed that Von Neumann’s argument for identifying the quantum mechanical entropy with the Von Neumann entropy, SðrÞ 1⁄4 ktrðr log rÞ, 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. The quantum mechanical entropy is generally taken to be the Von Neumann entropy SðrÞ 1⁄4 ktrðr log rÞ. Orly Shenker ([1999]) has claimed that Von Neumann’s argument in… CONTINUE READING
