Apparatus and method for injected spin echo sequences in a quantum processor. For example, one embodiment of a processor includes a decoder to decode quantum instructions to generate quantum microoperations (uops) and to decode non-quantum instructions to generate non-quantum uops, execution circuitry to execute the quantum uops and non-quantum uops, and a corrective sequence data structure to identify and/or store corrective sets of uops for one or more of the quantum instructions. The decoder is to query the corrective sequence data structure upon receiving a first quantum instruction to determine if one or more corrective uops exist, and if the one or more corrective uops exist, the decoder is to submit the one or more corrective uops for execution by the execution circuitry.
