Description
We study a class of driven dispersive resonator–qubit systems, consisting of a single resonator coupled to a network of qubits, with the interaction treated in the dispersive regime. The system dynamics is analyzed under different types of input fields, ranging from semiclassical electromagnetic drives to single-photon quantum excitations.
We develop a set of simplified theoretical models that capture the essential features of dynamics while retaining partial analytical tractability. These models are complemented by numerical simulations based on open quantum system techniques, implemented using the QuTiP framework. The resulting framework constitutes a flexible toolbox for the systematic study of dispersive cavity–qubit architectures, applicable to single-qubit and multi-qubit configurations and largely independent of the specific physical realization of the qubits. The methods can be extended and integrated with optimization and machine-learning techniques, enabling the efficient exploration of complex parameter spaces and protocol design.
While the approach is general and applicable to different qubit platforms, superconducting qubits provide a natural testbed for validating the proposed models. Possible applications include the analysis and optimization of driven quantum systems and their use in quantum simulation and information-processing tasks, and in metrology and sensing.
