Quantum Synth: a Quantum-Computing-based synthesizer

In this paper we present the Quantum Synth project, an interface between Qiskit and Max for controlling sound synthesis parameters encoded on the basis states of a quantum computer. With this representation, sound synthesis is obtained from the potential measured outcomes of a quantum circuit. The effects of using fundamental quantum operations as found in the Bell circuit, for the generation of entangled states, and the Grover’s search algorithm have been demonstrated. The interface has been designed to be used by music performers and composers in their creative process, and as a resource to both learn Quantum Computing and analyze the intrinsic noise of real quantum hardware.
