Took a while to come up with an adequate translation of 干渉触. Basically, it's a nonce technobabble word, but I 'know' that the author likely coined the term to describe some kind of weird quantum interference/entangling effect causing what would seem to be spooky action-at-a-distance "physical contact" to happen. Stared at the word for a while before I thought of "interferometer" from double-slit(ha!) experiments, then kludged it into an adjective.
That said, most people would probably have problems trying to understand the quantum technobabble, but in that case all one needs to know then is "Spooky quantum mechanics, yo!".
(Also, slit-mouth woman is a walking double-slit experiment! You're a genius, Ishiyumi-sensei.)

Interferometric contact with matter outside the body—!?
Weird quantum mechanics stuff, that's all you need to know.
