Bridge of $\Psi$'s: Quantum Circuit Optimization with Schr\"odinger Bridges
An arXiv preprint presents BOPS (Bridge of Ψ's), a method that treats quantum circuit optimization as a generative modeling task. Rather than applying fixed rewrite rules or algebraic identities, a model learns transformations from examples to produce shorter, lower-depth circuits.

BOPS could lead to learned circuit optimization passes that find non-local gate-count reductions missed by fixed rewrite libraries, inserted into existing transpiler pipelines as an offline pre- or post-processor.
Standard optimizers rely on local rewrite rules; a generative model trained on equivalent circuit pairs could propose globally compact structures. Equivalence checking is mature enough to verify candidate transformations before accepting them, reducing the risk of incorrect circuits.
