Add list of papers from Unitary Fund team members. The papers from the projects are scattered in the grants section, but maybe also those could be collected.

Adding to the list here:

https://arxiv.org/abs/2005.10921

https://arxiv.org/abs/2009.04417

https://arxiv.org/abs/2104.15044

https://arxiv.org/abs/2105.09902

https://arxiv.org/abs/2108.02237

Could also include a subsection for collaborations where UF staff members are involved, such as https://arxiv.org/abs/2101.05710, https://arxiv.org/abs/2104.09811.

This page could point to the https://github.com/unitaryfund/research repository and to the code-blocks in https://mitiq.readthedocs.io/en/latest/examples/mitiq-paper/mitiq-paper-codeblocks.html.

I think the solution to this could also resolve #39? I'll take a stab at today

#115 resolves this I think, reopen if needed
