Quantum error mitigation is a set of techniques aimed at reducing the effects of errors in quantum computers. 

Quantum devices are subject to environmental noise that degrades the quality of computations performed. While fault-tolerant quantum computing promises a solution to this problem, current quantum devices are limited by the number of qubits and relatively high error rates. To combat this in the near-term, researchers are investigating methods to improve the accuracy of noisy quantum computation. This approach, known as *quantum error mitigation*, involves using various techniques to extract the best signal from noisy measurement data.
