Photon pairs, squeezed light and the quantum wave mixing effect in a cascaded qubit system

R. D. Ivanovskikh, W. V. Pogosov, A. A. Elistratov +6

We develop a theoretical description of quantum wave mixing (QWM) in a cascaded waveguide-QED system of two superconducting qubits, where the probe is driven by an external coheren…
