We first design two primitive quantum voting rules, called quantum logical veto (QLV) and quantum logical nomination (QLN). Not only can they be used independently in scenarios where classical veto-like vote and nomination-like vote are applied, but they can also be used as building blocks to construct quantum majority vote. We also use them to define a quantum voting game to show that quantum ballots can achieve something that can never be achieved by classical ballots. The conjunction and disjunction from quantum computational logic are used to define QLV and QLN, which makes them relatively easy to be implemented by the current or near-future technology.

Nowadays, the majority of arbitrated quantum signature (AQS) protocols encrypt data qubit by qubit using the quantum one-time pad (QOTP). Despite providing robust data encryption, QOTP is not a good fit for AQS because of its susceptibility to many types of attacks. In this work, we present an efficient AQS protocol to encrypt quantum message ensembles using a distinct encryption technique, the chained controlled unitary operations. In contrast with existing protocols, our approach successfully prevents disavowal and forgery attacks.
