Like every other scientific discovery, weaponize it. I can imagine a few ways that one can disable advanced weaponry or cause harmful/adverse effects to weaponry, computer systems, and/or ammunition. I imagine that such a solution would cause the desired harm something without leaving a trace.

I don't see "distance" mentioned on the article, but I did see a temperature (118 K = -155 C)(which make it (currently) impossible to use outside a lab). The breakthrough is here though, and now someone must already be at work to see if this can be operated in battlefield/real-life conditions.

I remember on TBBT when they made a gyroscope-thingie-invention but it was 'THIS' big, and the army officer was pressing them to remake it 'that' small so it can be fitted on missiles (or whatever). Isn't this how it typically happens?
