Toward quantum-ensured privacy and voting
In my talk I will present a number of schemes that use quantum mechanics to preserve privacy. I will show that entangled quantum states can be useful in maintaining privacy. In particular, I will present a quantum-based voting scheme satisfying privacy requirements. A variation of these quantum-based schemes can be used for secure function evaluation. I will consider functions corresponding to group multiplication of group elements, with each element chosen by a different party. I will show how quantum mechanics can be useful in maintaining the privacy of the choices group elements.
Please note exceptional day and time.
