Matrix Multiplication Contest

Open quantum-circuit challenge

17 qubits vs. a data-center matrix problem.

One 65,536-dimensional matrix operator. Done densely on classical hardware, it’s ~563 trillion floating-point operations over ~192 GB of matrices. The community is compressing it into a single quantum circuit — and the score keeps falling. Beat the frontier and co-author the research paper.
