Collapse-binding quantum commitments without random oracles (Asiacrypt 2016)

We construct collapse-binding commitments in the standard model. Collapse-binding commitments were introduced by [CITE collapse] to model the computational-binding property of commitments against quantum adversaries, but only constructions in the random oracle model were known.
Furthermore, we show that collapse-binding commitments imply selected other security definitions for quantum commitments, answering an open question by [CITE short collapse].
