      abstract     = {This chapter examines the Variational Quantum Harmonizer, a
                      software tool and musical interface that focuses on the
                      problem of sonification of the minimization steps of
                      Variational Quantum Algorithms (VQA), used for simulating
                      properties of quantum systems and optimization problems
                      assisted by quantum hardware. Particularly, it details the
                      sonification of Quadratic Unconstrained Binary Optimization
                      (QUBO) problems using VQA. A flexible design enables its
                      future applications both as a sonification tool for auditory
                      displays in scientific investigation, and as a hybrid
                      quantum-digital musical instrument for artistic endeavours.
                      In turn, sonification can help researchers understand
                      complex systems better and can serve for the training of
                      quantum physics and quantum computing. The VQH structure,
                      including its software implementation, control mechanisms,
                      and sonification mappings are detailed. Moreover, it guides
                      the design of QUBO cost functions in VQH as a music
                      compositional object. The discussion is extended to the
                      implications of applying quantum-assisted simulation in
                      quantum-computer aided composition and live-coding
                      performances. An artistic output is showcased by the piece
                      $\textit{Hexagonal$ Chambers} (Thomas and Itaboraí, 2023).},
