| Dec 30, 2020 at 1:50 | comment | added | user87745 | @Frobenius To clarify, I think the homework-and-exercises tag should stay because it is clearly a type of question that would fall under that category. Just that it should not be deleted because it is a good question. | |
| Dec 29, 2020 at 21:23 | comment | added | Voulkos | @rand : Yes, you are right. But as you see in my comment above I address my point of view to the moderator QMechanic. I did not delete the "homework-and-exercises" tag. For your information "homework-and-exercises" in PSE is not necessarily a homework and/or an exercise in a textbook or in examinations. It could concern even self-study. The moderator, if disagrees, could delete my answer as giving complete solution to a "homework-and-exercises" type question that is considered as off-topic here. Have a good day. | |

| Dec 29, 2020 at 13:46 | comment | added | Voulkos | It's not good practice the "homework-and-exercises" tag to be removed by the OP of the question. | |

| Dec 29, 2020 at 1:27 | comment | added | user87745 | @Frobenius Very relatedly, it's an excellent way to introduce the concept of quantum tomography and to illustrate how the phases store the information about probabilities of non-commuting operators (non-commuting w.r.t. the operator in whose eigenbasis we are expanding). | |

| Nov 7, 2020 at 21:55 | comment | added | Voulkos | @Qmechanic : IMO, this question must not be tagged as homework-and-exercises since it's a chance for users to learn about Bloch sphere, a tool beyond the narrow frame of an exercise. If you don't agree I'll change my answer to a hint removing the results or I'll delete it at all. | |

| Nov 6, 2020 at 20:16 | comment | added | user2723984 | @rand do the same thing, but with $\langle \uparrow_x|\psi\rangle$ etc... , you will just have to calculate overlaps such as $\langle \uparrow_x|\uparrow_z\rangle$ etcetera and you'll be done | |
| Nov 6, 2020 at 20:15 | comment | added | J. Murray | This isn't a homework help site, so you'll have to reframe your question in a more conceptual way to avoid it being closed. That being said, you've used 1/3 of the information given to you, so I don't quite understand why you're not using the rest in exactly the same way. | |
| Nov 6, 2020 at 20:13 | comment | added | rand1 | @J.Murray can you give any hint on how to use the other information? | |
| Nov 6, 2020 at 20:12 | comment | added | J. Murray | Why haven't you used the rest of the information given to you? | |
