Holistic Error Mitigation Frameworks For Near-Term Computations

It is necessary to mitigate physical errors in order for NISQ computations to compute quantities with reasonable accuracy. Therefore NISQ programming stacks must include a robust error mitigation infrastructure supplementing principal quantum programs at compile time and operating at a high level of abstraction. We introduce an error mitigation framework consisting of routines built into a software stack aiming to return corrected data from programs run on NISQ devices. As a demonstration, we implement a variety of protocols which increase the accuracy of variational quantum eigensolver-style hybrid algorithms running on multiple NISQ devices.
