Quantum Computer Music. What the heck?

"A technological leap that will make current computation and AI systems look obsolete? Tapping into the properties and laws of quantum mechanics, the nascent field of quantum computing promises just that. Eduardo Reck Miranda, composer and pioneer in the field of AI and music, gives a brief overview of the history of computing and sound that lead to this new leap, and adds examples of his own music practice with quantum computing. ..."

Premiere of »Spinning« at Goethe-Institute in London, December 2022.

"... »Zeno« is a milestone for me. What I have achieved with a rudimentary quantum computer sporting only a few qubits would require rather sophisticated AI programming running on a state-of-the-art desktop digital machine. This reinforced my hunch that music technology is on the verge of a significant leap. The thought of what these new machines might afford to musicians in 20 or even 10 years is mind-boggling. But what is quantum computing? How can a quantum algorithm represent musical rules? How can the results of processing a quantum algorithm make music? ..."

The Bloch sphere, a geometric representation of a two-level quantum system. 

"... For more details about QuPoly, the paper »Teaching Qubits to Sing: Mission Impossible?« introduces an earlier incarnation referred to as QuSing. The underlying mechanisms are identical. The two above examples are only a glimpse of how quantum computing can be harnessed for music. There is a growing community of enthusiasts embracing this technology. They are developing innovative approaches to music making. Several of these were presented at the 2nd International Symposium on Quantum Computing for Musical Creativity, which took place in Berlin in October 2023. If you are interested in a more in-depth introduction to the emerging field of Quantum Computer Music, I recommend the book, Quantum Computer Music: Foundations, Methods and Advanced Concepts, published by Springer in 2022. ..."
