I just noticed that there is not "quantum-technologies" tag on physics.SE. There are various related tags such as quantum-computing, but many other realizations of quantum technologies also do not have a tag for themselves.
Quantum technologies are currently being realized all over the world and by far not limited to quantum computing, including for example quantum communication and quantum sensing (both do not have tags for themselves). Developing quantum technologies is one of the big frontiers of current physics research and also receiving much attention in the media.
Should there be a quantum technologies tag?
I am unsure what it would imply to introduce such a broad tag. For example, many existing questions may have to be retagged.
