Renyi entropy #45

Closed NicholasSynesi closed 1 year ago

NicholasSynesi commented 1 year ago

Could be interesting to look at something other than the von Neumann entropy, and shouldn't be too hard to implement.

As a quick aside I tried plotting the Renyi entropy as it was a very simple change. I found a few resources already and in the write up I plan to just make it a quick aside, but I was wondering if these graphs look like they should?

Here is my alpha = 0

which gives an interesting graph. You mentioned this corresponds to the purity in the notes, is this something that can be concluded from this graph? Also, is there any other plots of the Renyi entropy that you think could be interesting?

Quick correction, purity is alpha = 2, which is here
