Yes, they are the theoretically the most elegant way to deal with decoherence. They rely on an exotic state of matter, non-abelian anyons(many still working on verifying their existence), and winding discrete non-abelian anyons into a topological braid, which disperses the quantum state spatially, making it much more resilient against decoherence(obvious simplifications made). This is the specific type of quantum computation that Microsoft is pursuing ala Michael Freedman and co.

What's interesting about topological quantum computing is that these Majorana pairs are resistant to disturbances for the same reason that Cooper pairs are in superconductors.
