Add more 1q and 2q Pauli rotation equivalences

[tyrolize]

Summary

Fixes #7332

Details and comments

I noticed that in some equivalence relations the theta parameter is defined only for the first equivalence relation (see RZGate in the changed file). I wonder if this is the best practice.

seems there are still some issues with tests.. I'll look into this

Thanks for the PR @tyrolize! Could you also add the following translations, incl. tests:

• RYY -> RZZ
• RXX -> RZZ (this one is not automatically covered by the RZZ -> RXX entry)
• RZZ -> RYY

[tyrolize]

I'll have a look at this this week!

[Cryoris]

@tyrolize, are you still working on this? 🙂

[tyrolize]

yep, will try to look at this this week, sorry for the delays :)

[tyrolize]

@Cryoris I can't figure out what causes tests to fail.
Also, could you please point me towards the test file for translations?

[javabster]

Hi @tyrolize it seems like the test case test_cx_bell_to_ecr is failing in the test file test_basis_translator.py. I think this file is also where you should add some tests for your changes as well.

You can check in the contributing guidelines how to run the tests locally 😄
