After the interference.
Anatomy of a near-quantum computer.

From October 17 to November 22, 2025.

At the crossroads of science, art and poetry, Kaspar Ravel questions our relationship to machines through a sensitive and luminous work. For his third and final year of residency at Sorbonne University*, the artist explores unconventional computing, between scientific knowledge and cultural imagination. At the heart of this exhibition: a machine without electronic components. Instead, sheets of paper and metal diffract light like fragments of algorithms in action. This optical device, inspired by the quantum properties of light, gives substance to another way of thinking about data, calculation and memory.

Presented at the Wagner gallery in disassembled form, this machine becomes a traversable landscape. The visitor is like a photon, modified with each threshold crossed. The suspended layers become works in their own right, silent artifacts of a language still in the making.

Between high technology and craftsmanship, Kaspar Ravel weaves a work where fundamental research, textile history, and quantum fiction intersect. An invitation to look differently at what a machine can be, echoing the work that the artist developed as part of the NEMO biennial at Centquatre Paris from October 2025. 

OPENING in the presence of the artist on October 17 at 6:30 p.m.
