摘要:

我们提出了一个在量子退火(QA)框架下操作的素因子分解器。其思想是用基于QA的布尔逻辑电路实现乘法器的逆运算。我们设计了一个特定于应用程序的退火计算架构,有效地增加了可用的硬件预算有限的功能为代价的QA机。利用经典噪声源对超导磁通量子比特组成的QA逻辑门进行了电路模拟,证实了QA逻辑门的可逆操作。该电路采用Nb/AlOx/Nb约瑟夫森结超导集成电路技术实现和制造。我们还提出了一个2.5维的量子位芯片/芯片/封装基板结构的封装方案,实现实际的大规模QA系统。

英文摘要:

We propose a prime factorizer operated in a framework of quantum annealing (QA). The idea is inverse operation of a multiplier implemented with QA-based Boolean logic circuits. We designed the QA machine on an application-specific-annealing-computing architecture which efficiently increases available hardware budgets at the cost of restricted functionality. The invertible operation of QA logic gates consisting of superconducting flux qubits was confirmed by circuit simulation with classical noise sources. The circuits were implemented and fabricated by using superconducting integrated circuit technologies with Nb/AlOx/Nb Josephson junctions. We also propose a 2.5Dimensional packaging scheme of a qubit-chip/interpose /package-substrate structure for realizing practically large-scale QA systems.
