We explore the effective theory of a hybrid superconducting transmon qubit coupled to a quantum dot (QD), introducing tunable fermionic degrees of freedom into the transmon architecture. This coupling gives rise to Andreev bound states, whose interaction with the transmon’s bosonic modes leads to rich hybridization effects.
Using analytical and numerical techniques, we analyze how gate voltages control the system’s energy spectrum and dipole transition strengths, revealing signatures of charge-parity mixing and gate-dependent selection rules. Our findings offer insight into the design of hybrid qubits that leverage both superconducting and mesoscopic physics for future quantum technologies.
