I believe the channel_fidelity.py function should use the partial trace function from toqito instead of the one it's currently using from picos. Then, the commented out functions intest_channel_fidelity.py can be uncommented and be run (which would then increase the coverage). Does that make sense?

Thanks! Makes sense.

Nice. I like how the tests are also simpler from your changes as well. LGTM! Approved!
