Official implementation of "The Quantum Loom." We simulate Spacetime as a Discrete Topological Superfluid on IBM Heron (156-qubit) processors to computationally resolve the Hubble Tension, Dark Energy, and the Singularity.

Compiling equivariant quantum neural networks can break their symmetry at the structural level, with up to 22.5% CZ-count asymmetry between symmetry-related sparse-graph inputs on IBM Heron's Fez. We classify ansätze by where the input enters and fix the affected case via compile-once-and-relabel.
