Error Mitigation for Analog Simulators

Abstract

Analog quantum simulators have shown impressive results in regimes that are challenging to simulate with classical computational methods. However, the influence of noise hampers their use as precision simulators. Recently, digital computation in noisy systems has made extensive use of error mitigation strategies to recover quasi-exact results. Such techniques have not largely been adapted to analog quantum simulators. In this work, we target the dominant noise sources in analog simulation platforms by extending methods from digital computation to work within the restrictions of analog quantum simulators. We explore the feasibility of these methods in mitigating characteristic sources of noise for trapped ion and neutral atom devices.
