양자 회로 동작 검증을 위한 QCA 룩업 테이블과 QRAM을 이용한 유효성 확인

다국어 초록 (Multilingual Abstract)

Quantum-dot cellular automata (QCA) is a next-generation quantum circuit technology that is attracting attention for its size, power consumption, and speed of information transfer. A method of verifying circuits designed with QCA is a physical proof method. The physical proof method has the advantage of being able to verify the QCA circuit outside the simulation environment, but has the disadvantage that it requires a lot of computation. Therefore, this paper proposes a method for verifying a circuit using a QCA look-up table (QLUT). Verification using QLUT is a method of making an output value according to an input in a tabular format in advance. By using this method, it is possible to verify the circuit more concisely without having to perform a complicated operation of the existing physical proof. In this paper, the operation of QRAM (Quantum RAM) is verified by QLUT-based verification, and the existing physical proof and QLUT method are compared and analyzed.
