The example given is horribly wrong.
[edit]Use 1/4,1/4,1/2 to get the final state S=[[1/2,0],[0,1/2]]
The POVM's given are not positive and they are not the results of the multiplication shown. E0 shown has a -ve eigenvalue. E0+E1+E2 do not sum to 1.
This is an example of how not to do math. 2607:F2C0:E56E:56B:1C36:C470:3C0:D672 (talk) 16:22, 23 June 2023 (UTC)
- the example was indeed wrong, and doing the math right didn't result in particularly insightful operators. I removed the example and expanded a bit the section adding general considerations Luca (talk) 22:06, 23 June 2023 (UTC)
