Can ‘quantum musical agents’ really make a melody better?

The history of popular music has been shaped by technological innovations, from the invention of the electric guitar to the creation of the wobble bass. A recent study titled "Teleportation game: Quantum teleportation in multi-agent systems for interactive music" explores the potential of quantum computers in music production. Researchers introduce "quantum musical agents" that communicate by teleporting quantum states to one another.

These agents process musical phrases using Single Qubit Probability Amplitude Modulation (SQPAM) and Quantum Phase Estimation (QPE), potentially resulting in modified recordings.

The lead author of the study, Eduardo Miranda, is a composer and computer scientist who has previously created music using brain-computer interfaces, slime moulds, and quantum computers. His latest album, QUBISM, was entirely composed using quantum computers. However, the study does not include any audio samples, making it difficult to determine the exact output of the quantum musical agents.

The paper suggests that the agents are designed to support ambiguous and transformative interactions reminiscent of free jazz improvisation. The authors acknowledge that divergence and ambiguity are tolerated within their system. In other words, the quantum agents may occasionally play a wrong note.

One of the authors, Jonathan Stoppi, encountered a van advertising "Kangen Water," which claims to be hydrogen-rich, alkaline, and antioxidant. However, the scientific understanding of water chemistry contradicts these claims. The van's URL led Stoppi to a website selling Kangen Water, which further emphasizes its health benefits and potential to make plants fresh and alive.

Despite the author's earlier coverage of the supposed health benefits of alkaline and hexagonal water, the Kangen Water claims appear to be exaggerated.
