Makes high tech-level pure fusion nukes extremely difficult to control.

Cool ideas for high-tech materials science. Thanks.

So strange matter can be formed by squashing nuclear matter beyond some
critical limit - and industrially usable quantities can be produced?

Wow.
Is this an RPG setting, or described in a short story/novel?
