From: Tunable directional photon scattering from a pair of superconducting qubits
Power spectral density (PSD) measured in transmission (a, b) and reflection (c, d) at the digitizer for in-phase α = 0 (a, c) and out-of-phase α = π (b, d) modulation. The Stokes components are highlighted with dashed circles. Scattering schematics are shown as insets where blue (green) arrows represent the light scattered from qubit 1 (2) at ω0 ± Ω leading to constructive interference in a and d or destructive interference in b and c. Full Rayleigh peak heights are 1.9 and 1.6 V2 for the chosen settings in a and b.
