Open source projects tend to emerge when there is general access to the purpose of that project. You can't expect an open source project for Ocean-based Wind Turbine simulation or molecular synthesis of Organochloride compounds.
They're niche industries that require tremendous amount of upfront investment, in both physical assets to realize the utility of the open-source project, and knowledge-base required to operate the software.
On the other hand, you could have a piece of software that requires niche knowledge but its used literally everywhere - for e.g. OpenSSL. Not many people can contribute to it, yet it exists as open source. The point I am trying to make is that OpenSSL and your quantum hardware control software are very different things.
