Error mitigation - handling noisy quantum hardware — •Kathrin König and Thomas Wellens — Fraunhofer IAF, Freiburg, Germany

Currently available quantum computing hardware suffers from errors due to environmental influences, nearest-neighbour interactions and imperfect gate operations. To achieve robust quantum computing, there are techniques like error mitigation by zero-noise extrapolation [1]. To reduce the impact of gate errors on observable expectation values, arbitrary noise can also be converted into stochastic Pauli errors by so called noise tailoring [2]. We elaborate on the implementation of error mitigation on a superconducting quantum computer and its impact on the computation of expectation values.
