how do i write the z spin state using the spin state on x or on y?
Spin state, base transformation
Click For Summary
Discussion Overview
The discussion revolves around expressing the z spin state in terms of the spin states on the x or y axes. It touches on concepts from quantum mechanics, specifically related to spin operators and their algebra.
Discussion Character
- Exploratory, Conceptual clarification, Homework-related
Main Points Raised
- One participant asks how to write the z spin state using the spin states on the x or y axes.
- Another participant suggests that the responses provided may not be entirely helpful and encourages the original poster to seek out online explanations of the algebra of spin operators.
- A different participant notes that the original poster has already attempted an internet search for answers.
- There is a suggestion that a more focused question could lead to better responses once the original poster encounters specific difficulties.
- A participant compares the situation to seeking help from a professor or TA during office hours, emphasizing the importance of prior effort in understanding the topic.
Areas of Agreement / Disagreement
Participants do not reach a consensus on how to express the z spin state, and the discussion remains unresolved with varying suggestions on how to approach the problem.
Contextual Notes
Limitations include the lack of specific details on the algebra of spin operators and the need for further clarification on the original poster's understanding of the topic.

@usai you might not find the responses above completely helpful? :) :)
Seriously, kidding aside, PhysicsForums is generally better at helping people over the hard spots than laying out an entire lecture-equivalent tutorial (better done by textbooks and online course materials). So if you can get hold of a good online explanation of the algebra of the spin operators - several out there and some other poster may chime in with their favorite - and start in on it, come back with a more focused question as soon as you hit a hard spot you'll get better and more helpful answers.
Another way of thinking about it: Suppose you are taking a college-level intro to QM course as part of a physics bachelor's degree (which is about right for this topic and consistent with the I rating you gave the thread). You walk into your professor/TA's office during office hours with this question, the absolute first thing you're going to hear is "How far into the textbook/course notes did you get?". Same thing here, except with the general unstructuredness of the internet layered on top.
