Could you provide some example screenshots of how this node can be used, please?

Lastly, do qiskit-finance and qiskit-optimization not come with Qiskit by default? If not I'll add them to the setup script (though I would like to merge PR #100 first due to some changes I made to the script.

Finance and Optimization are deprecated from Qiskit and moved to 2 separate packages, super annoying :/

will work on changes asap

updated the Description of PR with example

I tried adding the qiskit-finance and qiskit-optimization packages to the setup script (526aca6842671139805f7fd2768350f625d480c5), but for some reason that causes random tests to fail on the CI. I have literally no idea why, best guess is that maybe there is some sort of conflict occurring between the packages?

I think this should be fixed now that PR #110 is merged, but for some reason the CI wasn't triggered on push. Probably a problem with GitHub Actions being down temporarily or something, so will have to test if it's fixed on next push.

I think the issue was due to the pyvenv.sh script incorrectly thinking Qiskit was installed when it wasn't. Below is the installation output:

Creating virtual environment at /home/runner/work/node-red-contrib-quantum/node-red-contrib-quantum/venv...
Successfully created virtual environment
Installing qiskit-optimization...
Successfully installed qiskit-optimization
Installing matplotlib...
Successfully installed matplotlib
qiskit is installed  <-- This shouldn't have happened
Installing qiskit-finance...
Successfully installed qiskit-finance
Installing pylatexenc...
Successfully installed pylatexenc

Once qiskit-optimization was installed, it caused the check for seeing if qiskit is installed to be a false positive. PR #110 improved the robustness of this check, so the issue should be avoided now.

Can we use this PR to change 'Shors' nodes icon? For now, it is the same as 'Grovers' icon.

I would suggest one of these two:
