  The paper concerns the protection of the secrecy of ballots, so that the
identity of the voters cannot be matched with their vote. To achieve this we
use an entangled quantum state to represent the ballots. Each ballot includes
the identity of the voter, explicitly marked on the "envelope" containing it.
Measuring the content of the envelope yields a random number which reveals no
information about the vote. However, the outcome of the elections can be
unambiguously decided after adding the random numbers from all envelopes. We
consider a few versions of the protocol and their complexity of implementation.
