Abstract: A quantum entanglement generator comprises two superconducting qubit elements, each having three electrodes, where n is an integer greater than or equal to, a coupling resonator disposed between adjacent superconducting qubit elements and a waveguide capacitively coupled to each of the superconducting qubit elements and to each other. The coupling resonator generates quantum entanglement between the adjacent superconducting qubit elements by acting a two-qubit gate between the adjacent superconducting qubit elements. The superconducting qubit elements emit the quantum entanglement as a propagating microwave photon into the waveguide, thereby generating a two-dimensional cluster state.
