Project Description:
Implementing the method described in 'Decoding quantum errors with subspace expansions' McClean et. al 2020. This approximates the post processing error correction method of projecting out all non codes states with a more relaxed projector containing a subset of the full stabiliser group for a quantum code.
Apart from the direct application to error mitigation, the ability to decode quantum errors without ancilla heavy syndrome measurements means this method is a NISQ friendly candidate for investigating the performance of quantum codes on real devices. I implement the beginnings of an open source library for this purpose and observe the results of a small toy problem.
