This work is part of the spintronics field. There are some good youtube videos about it:

If you can get an event that needs a wave above a certain height to trigger, you can make a gate by having input of waves a fraction of that height that, when they constructively interfere, exceed the threshold.

If your logic is based on wave interference, you may be able to get a lot of interesting behaviors even more useful than primitive logic gates.
