Features and benefits

  • Unbiased error mitigation

    QESEM offers powerful unbiased error mitigation, which improves accuracy and can be scaled with additional QPU time.

  • Application-agnostic performance

    QESEM is designed to work across many applications, increasing the accuracy of results for quantum circuits or observables, and optimizing performance with advanced circuit compilation.

  • Extended gate set

    Leverage mitigation with QEDMA-optimized fractional-angle Rzz(θ) gates to significantly reduce circuit depths.

  • Multibase observables

    Employ optimized mitigation for observables composed of many non-commuting Pauli strings in quantum chemistry and physics applications.
