Title: 使用Design Compiler的期权定价混合信号量子电路设计

Abstract: Prior studies have largely focused on quantum algorithms, often reducing parallel computing designs to abstract models or overly simplified circuits. This has contributed to the misconception that most applications are feasible only through VLSI circuits and cannot be implemented using quantum circuits. To challenge this view, we present a mixed-signal quantum circuit framework incorporating three novel methods that reduce circuit complexity and improve noise tolerance. In a 12 qubit case study comparing our design with JP Morgan's option pricing circuit, we reduced the gate count from 4095 to 392, depth from 2048 to 6, and error rate from 25.86\% to 1.64\%. Our design combines analog simplicity with digital flexibility and synthesizability, demonstrating that quantum circuits can effectively leverage classical VLSI techniques, such as those enabled by Synopsys Design Compiler to address current quantum design limitations.

Abstract: 先前的研究大多集中在量子算法上，常常将并行计算设计简化为抽象模型或过于简化的电路。这导致了一个误解，即大多数应用只能通过超大规模集成电路（VLSI）实现，而无法使用量子电路实现。为了挑战这一观点，我们提出了一种混合信号量子电路框架，该框架结合了三种创新方法以降低电路复杂度并提高抗噪能力。 在一项关于12量子比特的案例研究中，我们将我们的设计与摩根大通的期权定价电路进行了比较，结果表明我们减少了门的数量从4095到392，深度从2048减少到6，错误率从25.86%降低到1.64%。 我们的设计结合了模拟的简洁性和数字的灵活性及可合成性，证明了量子电路可以有效利用经典VLSI技术（例如由Synopsys Design Compiler支持的技术）来解决当前量子设计的局限性。
