Error mitigation for quantum approximate optimization
Anita Weidinger, Glen Bigan Mbeng, Wolfgang Lechner · Physical Review A · 2023
Quantum error mitigation involves reducing errors in hybrid quantum-classical algorithms, which is particularly relevant for near-term noisy quantum devices. The authors introduce an error mitigation technique based on redundant parity encoding of logical variables. They demonstrate the use of this technique by applying it to the quantum approximate optimization algorithm.
