Quantum Electronic Voting
Functionality
(Quantum) E-voting allows the process of vote casting and counting with the help of quantum communication and quantum mechanical systems. This functionality comes with a guarantee that votes remain secret i.e. no one can link a voter to his vote, and comes with properties of verifiability and impossibility of double voting. Electronic voting protocols consist of election authorities, talliers, voters and bulletin boards. All quantum e-voting protocols are divided into three phases, setup phase, casting phase, and tally phase. In the Setup phase voting choices are defined and protocol parameters are generated.
In the casting phase votes are generated and cast and in the tally phase election result is computed.

Use-cases
- Classical task
- Classical Electronic voting
Protocols
- Dual Basis Measurement Based Protocol
- Travelling Ballot Based Protocol
- Distributed Ballot Based Protocol
- Quantum voting based on conjugate coding
Properties
- An e-voting protocol is correct if the outcome is correctly computed in honest rounds without the presence of an adversary.
- Vote privacy means voters’ votes are private and there is no link between a voter and his vote.
- Impossibility of double voting allows voters to vote at most once
- Verifiability allows the verification of the results by voters and external auditors.
