Precise and effective control of the properties of the individual items in a coupled system is crucial to the study of quantum information and quantum simulation. In a system composed of coupled nonlinear resonators, the tunability of resonance frequency and nonlinearity attracts most interests since it leads to different regimes with significantly different physics. Here we report the local control of two capacitively coupled nonlinear microwave resonators in the driven-dissipative regime. Following calibration, both the frequency and the nonlinearity of the individual resonators can be controlled effectively. The ability to control the local properties of coupled nonlinear resonators paves the way for applications in quantum information and quantum simulation in the future.
