This project studies the non-linear interaction of photons with different arrangements of quantum emitters (two-level states) in one-dimensional photonic waveguides. Since absorbed photons alter the device seen by subsequently incoming particles of light this leads to effective photon-photon interactions. The goal is to use these mediated interactions between photons ultimately as gates in analog computation architectures. Here, I aim to propose strategies for time-resolved simulation of vibrational excitations in molecules beyond the harmonic mode approximation; either using the cross-Kerr effect to couple transmons in superconducting devices, coupling between photons and transmons via cavities, or an all-optical setup based on the mentioned mediated photon-photon interactions in waveguides.

本项目研究了一维光子光波导中不同量子发射体(二能级)排列的光子之间的非线性相互作用。由于被吸收的光子改变了随后进入的光粒子所看到的装置，这导致了有效的光子-光子相互作用。其目标是最终在模拟计算体系结构中使用这些中介的光子之间的相互作用作为门。在这里，我的目标是提出超越简谐模式近似的分子中振动激发的时间分辨模拟策略；或者使用交叉克尔效应来耦合超导器件中的透射子，通过腔耦合光子和透射子之间的耦合，或者基于前面提到的光波导中的光子-光子相互作用的全光学装置。
