中文摘要： 量子纠缠是量子计算和量子通信的物理基础，量子纠缠光频梳是量子计算硬件平台之一。基于硅基微纳谐振腔的量子纠缠光频梳具有体积小、与CMOS工艺兼容、易于集成等优点，与分光器、相位调制器等无源量子器件融合，构成硅基光量子芯片，可运行Shor、Grover等量子软件算法。同时采用CMOS工艺制备的经典集成电路和量子集成光路的无缝融合在经典计算和量子计算之间架起桥梁。本项目首先建立硅基微纳谐振腔的非线性薛定谔经典方程和量子动力学方程，据此编制Matlab数值仿真软件，优化硅基微纳谐振腔的几何结构设计和色散关系，达到硅基谐振腔级联四波混频效应的相位匹配条件，完成量子纠缠光频梳的理论方案设计。利用交大光纤国重实验室和罗切斯特大学光学中心先进的硅基光子学实验平台，进行硅基微纳谐振腔光频梳实验，验证理论结果，并研究硅基损耗、色散、SPM、XPM、TPA等对量子光频梳传输特性的影响，建立并完善硅基光量子学。

英文摘要： Quantum entanglement is the physical foundation of quantum computation and quantum communication, quantum entangled frequency comb is one of quantum computation hardware platforms. Entangled frequency comb based on silicon microresonator has many advantages such as portability,CMOS compatiblity, and integrability. It can be used to construct silicon chip for quantum computation,on which many quantum software algorithms such as Shor factoring algorithm, Grover algorithm can be demonstrated, together with passive quantum devices for example silicon beam splitter, phase modulator et al. The marriage of classical integrated electronic circuit and quantum integrated optical circuit, both of those can be fabricated by CMOS techniques, provides a bridge between classical computation and quantum computation. In our proposal, classical and quantum nonlinear Schrodinger equanions of silicon microresonator are firstly constructed. According to these equations,Matlab simulation softare will be programmed in order to optimally design geometric structure and dispersion relationship of silicon microresonator. When the phase matching conditions are satisfied of cascaded four wave mixing processes of silicon microresonator, the theoretical scheme of generating entangled frequency comb is finished. On the advanced platforms of silicon photonics of both State Key Lab in SJTU and the Institute of Optics in University of Rochester, the experiments of silicon optical frequency comb cam be implemented to test the theoretical prediction. Finally, the effects of the characteristics of silicon such as loss, dispersion,SPM, XPM,TPA et al on transmission of entangled optical frequency comb are investigated, the theory of quantum silicon photonics will be completed.
