Abstract

We propose a scheme to generate χ-type four-qubit entangled states by using superconducting transmon qubits (STQs) capacitively coupled to a superconducting transmission line resonator (TLR). The coupling between the STQs and the TLR can be effectively controlled by properly adjusting the control parameters of the STQs. The experimental feasibility of our scheme is also discussed.
