AI 中文摘要
我们提出了一种基于格雷码编码的可编程量子只读存储器，称为GQROM，旨在高效地将经典数据加载到量子电路中。该架构通过减少初始化开销和门致错误，缓解了近量子计算中的关键瓶颈。通过利用格雷码（其中连续地址仅相差一位），GQROM最小化了状态转换的复杂性。我们展示了该架构通过初始状态修改来访问目标数据的灵活性。整个设计，包括系统化的EDA流程，已在Qiskit平台上实现并验证，确认了其实际可行性。这些结果强调了GQROM作为可扩展且硬件友好的解决方案在量子电路中高效状态制备方面的潜力。
英文摘要
We propose a programmable quantum read-only memory based on Gray code encoding, termed GQROM, designed to efficiently load classical data into quantum circuits. This architecture mitigates critical bottlenecks in near-term quantum computing by reducing initialization overhead and gate-induced errors. By utilizing Gray code, in which consecutive addresses differ by only a single bit, GQROM minimizes state transition complexity. We demonstrate the architecture's flexibility in accessing targeted data through initial-state modification. The entire design, including a systematic EDA flow, was implemented and validated on the Qiskit platform, confirming its practical feasibility. These results underscore GQROM's potential as a scalable and hardware-friendly solution for efficient state preparation in quantum circuits.
