»Superposition Composition«
In the organizer's words:
In quantum mechanics, superposition describes the state in which a system is in several states simultaneously until a measurement is made and the state is determined. Repeated measurements reveal probabilities, the weighting of which then marks the final state. The "Superposition Composition" is an artistic-scientific experiment that translates the quantum mechanical principle of superposition into a musical form and will be performed at least twice a day from March to December in the UNESCO Quantum Year 2025.
The composition of the approximately 10-minute piano piece "Superposition Composition" contains built-in variances that are determined for each performance of the piece by real random numbers calculated by a quantum computer. Each performance of the composition is therefore different from all previous performances and simultaneously functions as a measurement on the acoustic quantum system, which resolves the superposition of the possible composition modules into a fixed state of playability. Only after a large number of performances/measurements does the final form of the composition crystallize through the frequency of the variants played. Through the acoustic output of the composition on a MIDI piano on the music balcony of the ZKM | Center for Art and Media Karlsruhe, we are able to carry out a "measurement" at least twice a day for nine months. The composition resulting from these measurements will be presented in a separate performance at the end of the project. An accompanying data visualization and explanatory materials will complement the installation.
When: daily at 11:00 am and 5:00 pm
Place: Music balcony
