 note = {Quantum metrology has a potential for achieving high sensitivity by harnessing quantum effects and can be applied in various areas ranging from material science to biology. Because the sensitivity is reduced by decoherence, many efforts have been made to recover the sensitivity under the effect of the decoherence. However, most of the researches have considered only statistical errors: reducing general systematic errors remains almost unexplored. Actually, systematic errors could nullify the advantage of the quantum strategy over the classical one. Here, we propose error-mitigated quantum metrology, a protocol to mitigate systematic errors by combining quantum metrology with quantum error mitigation. We demonstrate that our protocol mitigates systematic errors and recovers the superclassical scaling in a practical situation under time-inhomogeneous noise. Our results pave the way for hybrid structures with quantum computing and quantum metrology., Quantum metrology has a potential for achieving high sensitivity by harnessing quantum effects and can be applied in various areas ranging from material science to biology.
