Implementation of error mitigation for quantum computing machines

This invention describes a method to improve the accuracy of calculations performed on quantum computers. It works by first analyzing the inherent noise and stability of the quantum bits (qubits). Then, it runs the quantum calculation multiple times, artificially extending the execution time for each run. By comparing the results from these varied runs, it can statistically estimate the true, error-free outcome. The claims specify repeating this process for different measurements and multiple times to improve statistical reliability.

Why it matters: Filed in 2018, quantum computing hardware was still nascent. Since then, Noisy Intermediate-Scale Quantum (NISQ) devices have become more accessible and powerful, making practical error mitigation techniques like this one essential for extracting useful results from current machines.
