Abstract
Magic state is a powerful tool to make the fault-tolerant quantum computing universal.Thus obtaining high-fidelity magic states becomes one critical element to implement reliable fault-tolerant quantum computing.The author numerically simulates H-type magic state distillation based on 7-bit Steane code.The numerical simulation results show that the magic state distillation protocol is robust to slight perturbations about the H axis due to noise.Moreover,it is interesting for us to find that below fidelity threshold of distillable H-type magic states.Some states through repeated distillation can have higher fidelity with H-type magic state.
