Quantum Simulation Apparatus and Method Using Logical Qubit Synthesis

A quantum simulation apparatus using logical qubit synthesis, comprising:

• one or more processors;
• and
• a memory configured to store at least one program that is executed by the one or more processors,
• wherein the at least one program is configured to:
• generate a new virtual quantum device configured using magic qubits by dividing each logical qubit into multiple areas,
• extract logical qubit information from a target virtual quantum device that is a target of a logical Controlled NOT (CNOT) operation,
• synthesize the extracted logical qubit information into the new virtual quantum device,
• perform a logical CNOT operation in the synthesized virtual quantum device,
• extract logical qubit information from a result of the logical CNOT operation in the synthesized virtual quantum device, and
• synthesize the logical qubit information extracted from the result of the logical CNOT operation into the target virtual quantum device.
