In this paper we investigate the connection between quantum walks and graph symmetries. We begin by designing an experiment that allows us to analyze the behavior of the quantum walks on the graph without causing the wave function collapse. To achieve this, we base our analysis on the recently introduced quantum Jensen-Shannon divergence. In particular, we show that the quantum Jensen-Shannon d...

In a previous study by the author (1936) of over four hundred strains of non-gas-producing lactic acid rods isolated from fermenting substances, the differences in characters observed appeared to be more varietal than specific in nature. It was concluded that twelve previously described and named species were identical in whole or in part with Lactobacillus plantarum (Orla-Jensen) Bergey et al....
