Abstract: The distribution of entanglement between separated node of small- and large-scale quantum networks is a funtalmental task for many quantum communication and quantum information processing applications. Here, we investigate the deterministic generation and distribution of entanglement by driving distant qubits with the output of a non-degenerate parametric amplifier. We highlight the effect the bandwidth of the amplifier has on the final qubit-qubit entanglement. We will discuss the creation of complex multiqubit states when increasing the number of qubits just by choosing an adequate detuning pattern of the qubits. Our findings show how this passive protocol to generate entanglement between qubits is robust and applicable for microwave or hybrid quantum networks.
