1. A method of error correction for a quantum computer, comprising:
receiving a measurement of superposition state defined by a sum of a plurality of addends, wherein each addend of the plurality of addends is a product between a corresponding coefficient of a plurality of coefficients and a corresponding state of a plurality of states encoded with block unary encoding;
identifying at least one error state, of the plurality of states, having a string value that is not a block unary code string of a set of block unary code strings;
computing an updated measurement of superposition state based on the plurality of states without the at least one error state; and
providing the updated measurement to a quantum information processing (QIP) system to perform at least a portion of a quantum operation.
