Abstract: A method, system and computer program product for mitigating errors in measurements from a quantum system. A discriminator is trained to classify the measurement results of the quantum states of qubits as corresponding to a first quantum state (e.g., quantum state of 0) or a second quantum state (e.g., quantum state of 1). A first region of trust (corresponding to trusted measurements of a first quantum state) with a first discriminator boundary and a second region of trust (corresponding to trusted measurements of a second quantum state) with a second discriminator boundary are defined using the trained discriminator. If a shot-to-shot measurement result of a qubit state falls outside such regions of trust, the measurement result is rejected. In this manner, measurement errors from a quantum system are effectively mitigated, including measurement errors involving shot-to-shot measurement results of the quantum states read from the execution of the quantum circuits.
