Multi-Resonator-Assisted Multi-Qubit Resetting in a Network

We propose a quantum bath engineering method for the initialization of arbitrary number of flux-tunable transmon qubits with a multi-resonator circuit quantum electrodynamics (QED) architecture. Through the application of the microwave drives, we can prepare any number of qubits distributed among the network into arbitrary initial states (on the Bloch sphere surface). Taking into account the practically experimental parameters, we verify that the initialization process could be achieved in $1 \mu s$ with the fidelity in excess of 99\%. Moreover, due to the special structure of the circuit network, the initialization efficiency is independent on the number of (ideal, provided) qubits, as only a definite number of bosonic modes are involved in despite of the increasing number of the qubits to be initialized.
