Description

The SSVQE algorithm (https://arxiv.org/abs/1810.09434) is a generalization of VQE to find low-lying eigenstates of a Hermitian operator. This specific implementation of SSVQE carries out one optimization procedure using weights.

Hi @JoelHBierman :)

Can you plain text your description please

[frankharkins]

Also, @JoelHBierman can you try to keep the description ~30 words? For example:

The SSVQE algorithm (https://arxiv.org/abs/1810.09434) is a generalization of VQE to find low-lying eigenstates of a Hermitian operator. This specific implementation of SSVQE carries out one optimization procedure using weights.

This description is just for the qiskit.org/ecosystem web page, where users will work out if the project is what they're looking for. They'll click through to your repo for more details on how it works.

[JoelHBierman]

I see, yes I'll shorten the description and move the rest to the README.

Standard tests

❌ The submission didn't pass the standard check.
Please follow minimal requirements for project or/and add ecosystem.json configuration in the root of the project.
Read more here https://github.com/qiskit-community/ecosystem/blob/main/docs/project_overview.md#adding-project-to-the-ecosystem.

Stable tests

⚠️ The submission didn't pass the stable check.
This means your project doesn't work with the latest version of Qiskit.
This is purely informational and doesn't affect your project joining the Ecosystem, but you may want to investigate the problem.

Development tests

⚠️ The submission didn't pass the development check.
This means your project might not work with the next version of Qiskit.
This is purely informational and doesn't affect your project joining Ecosystem.

Hi @JoelHBierman
Can you add the ecosystem.json file at the root of your repo with something like that :

{
    "dependencies_files": [
        "requirements.txt",
        "requirements-dev.txt"
    ],
    "extra_dependencies": [
        "pytest"
    ],
    "language": {
        "name": "python",
        "versions": ["3.9"]
    },
    "tests_command": [
        "pytest"
    ],
    "styles_check_command": [
        "pylint -rn ssvqe test"
    ],
    "coverages_check_command": [
        "coverage3 run -m pytest",
        "coverage3 report --fail-under=80"
    ]
}

[JoelHBierman]

Yes I'll work on that and add it shortly.

[JoelHBierman]

I have added this file along with the other files from the ecosystem template that were missing.

Can some of the settings in .pylintrc be customized or are these strict standards that all packages in the community repo must adhere to? Using the defaults, I do not think this package would pass the linting tests without some extensive re-writing with regards to the number of class attributes, variables, ect...

We do not check the lint anymore, maybe one day we will but today we are not :)

hello @JoelHBierman! You joined the Qiskit Ecosystem a little while ago and I just wanted to check in and let you know of some follow up actions you can take to make the most of joining the program, if you're interested:

💬 Join other Qiskit ecosystem developers in the Slack channel #qiskit-ecosystem (if you are not in the Qiskit workspace yet, you can sign up here: https://qisk.it/join-slack)

🧠 Help us define the future of the Qiskit Ecosystem: we recently started an RFC on how the Ecosystem should be structured. It is very draft-y at the moment, but you can subscribe for notifications here Qiskit/RFCs#46 to participate in that discussion.

📣 Would you like to showcase your project to the Qiskit community? A couple of things you can do to raise awareness for your project:

• write a blog for your project (reach out to Abby Mitchell via slack or email if you'd like to be featured on the Qiskit Medium)
• Participate in Qiskit Demoday. (reach out to Luciano Bello via slack or email to request a slot to demo your project)

Great having you as a part of the ecosystem!
