One of the major challenges in the Noisy intermediate-scale quantum (NISQ) era is the lack of a general error mitigation technique demanding minimal additional resources. The protocol developed in this work is particularly useful in the NISQ era, as it does not require extra qubits, can be applied to different types of noise models and quantum data, and is more powerful than existing techniques in many situations. This generic protocol can be directly applied to a variety of algorithms running on near-term quantum devices.
