Abstract: The test of the superconducting quantum computing chip requires dozens or even hundreds of high-frequency microwave signal inputs. The ordinary microwave signal source generally only has 1~2 channels, which is far from meeting the test requirements. If multiple signal sources are integrated to expand the signal channel, it will be not only bulky and expensive, but the synchronization control of the signal source will be also a difficult problem. Aiming at the above problems, based on the power amplifier and power division technology, in this paper,,a method of equal-amplitude expansion of one output of the microwave signal source has been proposed, and a signal source equal-amplitude expansion device integrating attenuator, power amplifier and power division module has been designed. Then an experimental platform has been built with microwave signal source, spectrum analyzer, network analyzer and other measuring instruments to carry out experimental research on the performance of the designed signal source expansion device and verify the microwave signal source expansion method based on power amplifier and power division technology. The experimental results show that the proposed method can ensure that the amplitude and frequency of the extended signal are highly consistent with the source signal, and the signal phase of each extended channel can be kept stable for a long time, which meets the requirements of superconducting quantum computing chip testing.
Key words : quantum computing,;chip testing;RF signal source,;channel expansion,;power amplifier

    量子計(jì)算是一種遵循量子力學(xué)規(guī)律調(diào)控量子信息單元進(jìn)行計(jì)算的新型計(jì)算模式[1]。量子計(jì)算機(jī)的理論模型是用量子力學(xué)規(guī)律重新詮釋的通用圖靈機(jī)[2],。從計(jì)算的效率上,,由于量子力學(xué)疊加性的存在,某些已知的量子算法在處理問題時(shí)速度要大大快于傳統(tǒng)的電子計(jì)算機(jī)[3-4],。量子計(jì)算芯片本身的物理架構(gòu)是多輸入多輸出,,在芯片測(cè)試過程中,需要幾十甚至上百路高頻微波信號(hào)作為輸入[5-6],。量子超導(dǎo)計(jì)算芯片的測(cè)試需要幾十甚至上百路高頻微波信號(hào)輸入,,普通微波信號(hào)源一般只有1~2個(gè)通道,遠(yuǎn)遠(yuǎn)不能滿足測(cè)試需求,;若集成多個(gè)信號(hào)源以擴(kuò)展信號(hào)通道,,不但體積龐大,成本昂貴,,信號(hào)源的同步控制也是一個(gè)難題,。

    本文針對(duì)上述問題,基于功放及功分技術(shù),,提出了對(duì)微波信號(hào)源的一路輸出進(jìn)行等功率擴(kuò)展的方法,,設(shè)計(jì)了集成了衰減器、功放和功分模塊的信號(hào)源等幅擴(kuò)展裝置,。利用微波信號(hào)源,、頻譜儀、網(wǎng)分等測(cè)量?jī)x器搭建實(shí)驗(yàn)平臺(tái),,對(duì)所設(shè)計(jì)信號(hào)源擴(kuò)展裝置的性能開展實(shí)驗(yàn)研究,,同時(shí)驗(yàn)證基于功放、功分技術(shù)的微波信號(hào)源擴(kuò)展方法,,并對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行了分析,。
