  Quantum candies (qandies) is a pedagogical simple model which describes many
concepts from quantum information processing (QIP) intuitively, without the
need to understand or make use of superpositions, and without the need of using
complex algebra. One of the topics in quantum cryptography which gains research
attention in recent years is quantum digital signatures (QDS), involving
protocols to securely sign classical bits using quantum methods. In this paper
we show how the "qandy model" can be used to describe three QDS protocols, in
order to provide an important and potentially practical example of the power of
"superpositionless" quantum information processing, for individuals without
background knowledge in the field.
