      abstract = {Quantum computing is at an exciting time, with practical  quantum processors coming closer to experimental  realization. Yet a major challenge in building a practical  quantum computer is to generate and manipulate interactions  between its many components. Superconducting (SC) qubits  are promising candidates not only because they have strong  coupling and high-fidelity readout, but also for allowing  versatile parametric control that can realize different  effective interactions at will, which might be difficult to  achieve through other means. In this thesis, we start from  the simple example of parametrically flux modulated SC  qubit and demonstrate its application towards quantum  communication between remote SC modules. We then move on to  discuss the parametric modulation of the light-matter  interaction strength, where we introduce a novel SC tunable  coupler device that allows for the direct dc-flux control  of qubit-qubit or qubit-cavity coupling strength without  sacrificing qubit coherence, as well as the convenient  realization of blue- and red-sideband interactions through  appropriate choice of parametric flux-modulation frequency.  By engineering the dissipative system-environment  interactions through sophisticated parametric control of  this tunable coupler device, we achieve the autonomous  stabilization of arbitrary qubit states, in a manner akin  to laser cooling in atomic physics. Finally, we present our  on-going experimental effort of extending the idea of  autonomous stabilization to autonomous quantum error  correction, an important step towards the ultimate  realization of universal quantum computer.},
