Quantum Representations of Sound: From Mechanical Waves to Quantum Circuits

Abstract

This chapter discusses methods for the quantum representation of audio signals. Quantum audio is still a very young area of study, even within the quantum signal processing community. Currently, no quantum representation strategy claims to be the best one for audio applications. Each one presents advantages and disadvantages. It can be argued that quantum audio will make use of multiple representations targeting specific applications. The chapter introduces the state of the art in quantum audio. It also discusses how sound synthesis methods based on quantum audio representation may yield new types of sound synthesizers.
