Parametric modulation, valued for its versatility, is widely employed in superconducting circuits for quantum simulations and high-fidelity two-qubit gates. Conventionally, the qubit coupling strength is determined by the amplitude of the parametric flux pulse, which affects the qubit parameters dramatically. In this paper, we propose and implement a phase-modulation scheme to tune the interaction strength via adjustment of the relative phase between the parametric flux pulses applied to two coupled qubits. We characterize this modulation for sideband couplings, at both sweet and off-sweet spots, achieving a broad range of coupling strengths, as confirmed by both population dynamics and spectroscopy methods. This approach enables phase-controlled modulation of coupling strength, providing a promising candidate for parametrically driven quantum simulations and gate operations.

This repository contains data and a jupyter notebook that were used to analyze them and create the figures for the manuscript: "Origins of microwave losses in superconducting circuits made with silicon-on-insulator substrates". The Qcodes databases (.db) contain the raw data. csv files contain analyzed and fitted data used for generating the figures. Python scripts (.py) used for the analysis are included. txt files contains the results of simulations that are used for Figure 4.The notebook (.ipynb) calls the different files and generate the figures.
