Quantum voting via NV centers in diamond
D. B. Horoshko, Kilin Sergei Ya.
Abstract
We describe a scheme for quantum anonymous voting of n participants based on the single nitrogen-vacancy centers in diamond. The scheme requires a bipartite entanglement creation between the electronic spins of the two distant NV centers, unitary operation of NV electronic spin together with n nearby nuclear spins of carbon isotopes, and one projective measurement of the electronic spin state - optical readout. As a result, the quantum anonymous voting protocol can be realized, making any attempt of the tallyman to learn who voted which way detectable.
