| contents | We investigate the static properties of 0-$π$ Josephson junctions, with particular emphasis on their application in superconducting quantum circuits. Using a theoretical framework based on the sine-Gordon equation, we analyze the phase evolution for 0-$π$ junctions under various boundary and excitation conditions. These junctions, characterized by spatially varying phase shifts, offer promising configurations for qubit implementations due to their intrinsic symmetry and potential robustness against decoherence. We explore the energy landscape, quantized levels, and switching dynamics relevant for qubit state manipulation. Additionally, we present models for phase, flux, and charge qubit designs, emphasizing their operational principles and readout mechanisms. This work provides insights into the engineering of Josephson-based qubits and supports their continued development as scalable components for quantum information processing. |
