[unitaryhack] Added qiskit backends and tested

[RamAIbot]

I have added the code to use qiskit backend simulators in the "execute_with_shots" function. The corresponding test file is in "testing.py"

I have tested using 3 simulators of the qiskit. The circuit I tested with is the bell state circuit.

Fixes #1163

Hello @RamAIbot, thank you for submitting a PR to Mitiq! We will respond as soon as possible, and if you have any questions in the meantime, you can ask us on the Unitary Fund Discord.

thanks for the PR, @RamAIbot, you're off to a good start! I see the validation is failing- looks like there are a couple issues with types.

Also, I noticed you commented out some lines, can you remove them? Commented out lines can make the code "cluttered", and we can always get the original back, there are multiple ways to do that in Git.

Hi @Misty-W ,
I edited my code and it works for the test function which I created. But the problem is that it didn't work on the
test_execute_with_shots() function in test_qiskit_utils.py since I am not sure where to get the simulator name and other parameters I defines in my execute_with_shots function.

If possible can we have a discord meeting to discuss on this.

[Misty-W]

Sure, I can meet you tomorrow. I’m in the US Pacific time zone
