We present a scalable quantum-bus-based device for generating theentanglement on microwave photons (MPs) in distant superconducting resonators(SRs). Different from the processors in previous works with some resonatorscoupled to a superconducting qubit (SQ), our device is composed of some 1D SRs$r_j$ which are coupled to the quantum bus (another common resonator $R$) inits different positions simply, assisted by superconducting quantuminterferometer devices. By using the technique for catching and releasing a MPstate in a 1D SR, it can work as an entanglement generator or a node in quantumcommunication. To demonstrate the performance of this device, we propose aone-step scheme to generate high-fidelity Bell states on MPs in two distantSRs. It works in the dispersive regime of $r_j$ and $R$, which enables us toextend it to generate high-fidelity multi-Bell states on different resonatorpairs simultaneously.
