Performance¶
The performance of the System Model H1 emulator is measured in the fidelity to hardware. With inclusion of accurate and up-to-date noise models, the System H1 Emulator can provide a high-fidelity representation of System Model H1 output. Fidelity is verified at Quantinuum by comparison between the emulator and hardware outputs. However, noise models cannot fully capture the behavior of System Model H1; users should expect some variance. In the case of exceptional or unexplained variance, users should contact Quantinuum technical support at QCsupport@quantinuum.com to discuss the circuit and results.
