Abstract: Disclosed is a method for a logical operation performed by a quantum computing device, which may include: acquiring a logical qubit in which a physical qubit is encoded with a surface code; when performing a logical Hadamard operation in the logical qubit, and performing a first operation using a first joint measurement, performing a boundary flip; performing the first operation by using a second joint measurement other than the first joint measurement in the boundary-flipped logical qubit; and changing an order of the logical Hadamard operation after a step of performing the first operation by using the second joint measurement.

Abstract: Disclosed is a minimum searching method for searching a minimum in N (N is a natural number) data by a computing device including at least one processor. The method for searching the minimum may include: determining a threshold; initializing Qubits to include indexes representing addresses in which the N data are recorded, respectively, and the threshold in a superposition state; returning, from a superposition-state index, superposition-state data corresponding to the superposition-state index through a quantum memory; comparing the superposition-state data with the threshold in parallel through a quantum comparator (Q-comp); and searching the minimum based on the comparison result.

Abstract: Disclosed is a method for a logical operation performed by a quantum computing device, which may include: placing a data patch in which information is stored and computed, and a first ancilla patch which is consumed during a logical operation at a predetermined first interval; placing a first logical ancilla qubit between the data patch and the first ancilla patch; placing a second logical ancilla qubit to have a predetermined distance from one side of the first ancilla patch; and performing a joint measurement utilizing the data patch and the first ancilla patch.
