Abstract: Disclosed herein is an apparatus and method for executing a magic state distillation circuit in a logical qubit quantum system. The apparatus outputs a distilled magic state |Y>L by executing a magic state |Y>L distillation circuit in which multiple multi-target CNOT operations are performed in parallel and outputs a distilled magic state |A>L by executing a magic state |A>L distillation circuit in which multiple multi-target CNOT operations are performed in parallel. The magic state |Y>L distillation circuit is configured with three code blocks, code blocks 1 and 2 being configured with multiple multi-target CNOT operations and code block 3 being configured with SL operations and measurement operations, and the magic state |A>L distillation circuit is configured with three code blocks, code blocks 1 and 2 being configured with multiple multi-target CNOT operations and code block 3 being configured with TL+ operations and measurement operations.
