ePrint Report: General Non-interactive Quantum Commitments Are Compatible with Quantum Rewinding

Jun Yan

In this work, we show that general non-interactive quantum commitments (allowing quantum computation and communication) to classical messages are compatible with current-known quantum-rewinding techniques. Specifically, we first propose a definition of collapse-binding of quantum commitments which generalizes from its post-quantum counterpart and is shown to work well with quantum rewinding. Then we show that thus defined collapse-binding is equivalent to the conceivably minimal unique-message-binding. This in particular …
