Disclosed is an operating method of a surface code-based quantum simulation device including physical qubit storage, which includes storing initialized entanglement states of logical qubits corresponding to different distances, receiving a surface code-based initialization request corresponding to a specific distance, and storing an initialized entanglement state of a logical qubit corresponding to the specific distance from among the initialized entanglement states of the logical qubits corresponding to the different distances in the physical qubit storage.

Quantum simulation device and operating method of quantum simulation device

Disclosed is a quantum computing system including a first quantum chip including first physical qubits, a second quantum chip including second physical qubits, and a management device. The management device includes a physical qubit layer that manages physical qubit mapping including information about physical channels between first and second physical qubits, an abstraction qubit layer that manages abstraction qubit mapping including information about abstraction qubits and abstraction channels between the abstraction qubits based on the physical qubit mapping, a logical qubit layer that divides the abstraction qubits into logical qubits and to manage logical qubit mapping including information about logical channels between the logical qubits, based on the abstraction qubit mapping, and an application qubit layer that allocates at least one logical qubit corresponding to a qubit request received from a quantum application program based on the logical qubit mapping.
