Optimized QED intervals plus steady-state extraction enable PEC+QED to deliver 2-11x lower error than PEC alone on Iceberg codes for QAOA.
QLLVM delivers an LLVM-based end-to-end co-compiler that unifies classical HPC and quantum programs into one executable, with a three-stage quantum path via MLIR and QIR that reduces circuit depth and gate counts on MQTBench versus prior compilers.
Authors propose implementing the non-unitary Jastrow-Gutzwiller operator via cascaded VQE on quantum hardware and demonstrate it for the Hubbard model on IBM Q Lagos.
