Abstract
We propose a multi-resonator superconducting circuit to create the entanglement state between resonators which are specially arranged. One high-frequency resonator is placed in the middle working as a quantum bus and has two superconducting quantum interference device (SQUID) ends which function as effective boundaries. The other two resonators are vertically placed on sides and the magnetic flux created by these two resonators modulates the boundaries of the middle resonator, which in turn creates a nonlinear interaction between resonators. This coupling introduces opto-mechanical type Hamiltonian terms which can be used to generate a Bell state between two high-quality resonators with fidelity of 99.2% for practical parameters. The strength of the opto-mechanical terms is tunable, which meets the cure to the crosstalk in quantum computing and allows the possibility of large-scale integration of resonators and all-resonator quantum computing.
