There seems to be numerous work about the distillation protocol of the $T$-magic state $$ \frac{1}{\sqrt{2}}(|0\rangle+e^{i\pi/4}|1\rangle). $$

Similarly, I am wondering if it is possible to distill a $\theta$-magic state $$ \frac{1}{\sqrt{2}}(|0\rangle+e^{i\theta}|1\rangle). $$

Can we achieve it for arbitrary angle $\theta$? If not, what are the conditions for distillable $\theta$?

    Could you comment a little bit more on allowed operations? For example, could I distill $|H\rangle$ magic states and use that those along with Clifford gates give universal quantum computation (and hence I can to any degree of accuracy rotate a qubit to your desired state)? Or is that off-limits? – user196574 Nov 19 '23 at 20:48
  • @user196574 No strict requirements. Just make sure every step can be achieved (in principle) fault-tolerant. – Yunzhe Nov 20 '23 at 05:06
