Item Simulation and experimentation of a rat-race in superconducting conditions(2024-05-25) Jalli, Nico; Mukhanova, Ekaterina; Sähkötekniikan korkeakoulu; Turunen, MarkusThis work demonstrates a unique design for a superconducting CPW on-chip rat-race coupler. The purpose of the rat-race is to function as an interferometer for phasesensitive experiments in quantum optics. The function of the on-chip rat-race was first investigated using simulation software. The simulations showed that the design was workable, and experiments were subsequently conducted to investigate the rat-race’s properties. A sample on-chip rat-race was made for experimentation, and an experimental apparatus was constructed. The results were then compared to a PCB rat-race that was tested in the same apparatus. The comparison showed that the on-chip rat-race worked as well as the PCB rat-race.
