Sing and Measure: Sound as Voice as Quanta

Parallelism represents an essential aspect of human mind/brain activities. One can recognize some common features between psychological parallelism and the characteristic parallel structures that arise in quantum theory and in quantum computation. The article is devoted to a discussion of the following questions: a comparison between classical probabilistic Turing machines and quantum Turing machines. possible applications of the quantum computational semantics to cognitive problems. parallelism in music.
