Quantum Music

Quantum theory is a promising source of inspiration for experimental electronic music [1]. In this framework, we have recently introduced the concept of Quantum Notes [2]. A Qunote is a specific musical concept that follows the principles of quantum mechanics: superposition, coherence/decoherence, and entanglement. Qunotes are like Qubits but with musical notes instead of binary information. In a classical composition, a note would have to be in one state, ie. one pitch value, if we consider only this parameter. In contrast, the quantum state of a qunote is represented by a linear superposition of a defined number of pitch values. It’s only when the piece of quantum music is played (measured) that a qunote collapses into a defined state. Each time you play the same qunote, you may obtain different notes depending on the probability amplitudes. This results in many possible interpretations of the same score. As a consequence, when composing, you need to think at all the possible interpretations. You are composing with probability amplitudes instead of fixed notes.
