The paper compares fixed circuit partitioning with TeleSABRE, a routing method that jointly changes qubit layout, local SWAPs, and inter-processor teleportation for distributed quantum-chemistry circuits. It evaluates UCCSD, UpCCD, and UpCCGSD on hydrogen chains using two fermion-to-qubit mappings. TeleSABRE requires more than an order of magnitude fewer estimated Bell pairs, but this is not a runtime or accuracy result.
