More specifically, the important fact is that it's impossible for three particles to be (maximally) entangled simultaneously. So you can verify that no one eavesdropped when you agreed your one-time-pad.

Have you seen this recent result http://news.mit.edu/2018/physicists-create-new-form-light-02....

Does it change your thoughts on the utility of quantum cryptography?

They get three photons to be entangled, but not "maximally entangled" in the (impossible) way that would be needed for someone to listen to a communication without being detected.
