The state vs non-state discussion is still ongoing. The Stanford study linked above highlighted that there is a change in brain activity during hypnosis but there is also evidence for the non-state theories around expectancy, perception etc.
When I say 'state', I don't necessarily mean a distinct cognitive state, instead, I'm describing the characteristics: heightened suggestibility induced by expectation and focused attention.
