AI Commentary
This article demonstrates a concrete, artistic application of quantum teleportation by turning noisy NISQ qubits into expressive “quantum whispers” that drive real‑time musical improvisation among multiple agents and human performers. By encoding melodic parameters with single‑qubit probability amplitudes and coordinating agents through teleportation, the work showcases how decoherence can be harnessed as a creative resource rather than merely a limitation—a perspective that could inspire new interaction paradigms for future quantum‑networked devices. The approach also provides an early prototype for distributed quantum‑internet ensembles, suggesting that quantum communication protocols may soon find roles beyond computation in collaborative, interactive media.

Summary
This paper introduces an interactive music system with quantum musical agents that communicate by teleporting quantum states to one another. Human performers interact in real time with agents whose melodic and rhythmic behaviours are encoded as quantum states using Single Qubit Probability Amplitude Modulation (SQPAM) and structured through Quantum Phase Estimation (QPE). Up to three agents are combined within a single quantum circuit, with directed communication via quantum teleportation. We are interested in supporting ambiguous, transformative interactions reminiscent of free Jazz improvisation. Therefore, rather than treating noise and decoherence as limitations, the system embraces NISQ-era constraints as creative affordances, framing agent communication as quantum whispers, that is, deliberate, musically expressive imperfections in state transfer. We provide demonstrations and analyses based on melodic correlation, pitch-set distance, and state fidelity, where a continuum between imitation and divergence can be observed. We developed a tunable interpretation method to assess how agents reinterpret teleported states. This work positions teleportation as a promising interaction mechanism for agent-based quantum computer music and outlines future directions toward distributed ensembles connected via the Quantum Internet.
