Error rates

Definition

Error rates refer to the frequency at which errors occur in a given process or system, typically expressed as a percentage of total operations. In the context of quantum computing, particularly in boson sampling, error rates are crucial for understanding the reliability and accuracy of quantum computations compared to classical ones. High error rates can undermine the advantages of quantum supremacy, as they may lead to incorrect outputs that misrepresent the capabilities of quantum devices.
