| Mar 12, 2021 at 14:59 | comment | added | Norbert Schuch | @ZeroTheHero Good point, which links back to the question about the motivation behind wanting to show such a bound (there might be scenarios if these are not actual spins - though one would indeed expect that for any physical scenario, sigma would be a unit-ful operator.) | |

| Mar 11, 2021 at 21:20 | comment | added | Norbert Schuch | Is there a motivation behind this question? (I'm asking since often there might be a better answer for the original problem.) | |
| Mar 11, 2021 at 20:59 | comment | added | m137 | There was a typo in the sign, yes. I meant to put just upper bounds based on the operator's spectrum. | |
