I know that you can share artifacts between jobs of the same workflow...
But how can I share artifacts across different workflows?

GitHub has now added a REST API for downloading artifacts. Basically you do
GET repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}
And then you'll have to look for Location: in the response, and then access that url to download the artifact. The url is valid for 1 minute.
There's a GitHub Action that uses the API above that you can easily add to your workflow. I use it like this
- name: Download artifact
uses: dawidd6/action-download-artifact@v2
with:
workflow: ${{ github.event.workflow_run.workflow_id }}
workflow_conclusion: success
Read more about it here: https://github.com/dawidd6/action-download-artifact
Probably not yet doable:
After a workflow ends, you can download an archive of the uploaded artifacts on GitHub by finding the workflow run in the Actions tab. GitHub does not currently offer a REST API to retrieve uploaded artifacts.
If you need to access artifacts from a previously run workflow, you'll need to store the artifacts somewhere. For example, you could run a script at the end of your workflow to store build artifacts on Amazon S3 or Artifactory, and then use the storage service's API to retrieve those artifacts in a future workflow.
Just for posterity.
I wanted to share some lightweight contextual strings amongst workflows and created this https://github.com/marcoslopes/git-notes-action.
My specific use-case was to have different workflows dealing with build and deploy. Build would create an ami with packer and Deploy use that created image to be deployed with terraform.
As I am writing this I realise I could have added the sha as a tag on the image itself and search for it through the cli, oh well.
Looks like the related feature issue is download-artifact/issues#3, which references the dawidd6/action-download-artifact action that @Tobbe mentions in his accepted answer above.
