1. A method for a logical CNOT operation of quantum logical qubits, which is performed by a quantum computing device, the method comprising:
arranging a plurality of logical data qubits in a first horizontal column;
arranging a plurality of logical ancilla qubits corresponding to the plurality of logical data qubits, respectively as a second horizontal column which is different from the first horizontal column to correspond to the plurality of logical data qubits, respectively; and
performing logical controlled NOT (CNOT) for a first logical data qubit and a second logical data qubit among the plurality of logical data qubits,
wherein each of the plurality of logical ancilla qubits includes an intermediate logical qubit.
