Propagating Wigner-Negative States Generated from the Steady-State Emission of a Superconducting Qubit
Yong Lu, Ingrid Strandberg, Fernando Quijandría +3
We experimentally demonstrate the steady-state generation of propagating Wigner-negative states from a continuously driven superconducting qubit. We reconstruct the Wigner function…

Numerical study of Wigner negativity in one-dimensional steady-state resonance fluorescence
Ingrid Strandberg, Yong Lu, Fernando Quijandría +1
In a numerical study, we investigate the steady-state generation of nonclassical states of light from a coherently driven two-level atom in a one-dimensional waveguide. Specificall…

Steady-state generation of Wigner negative states in 1D resonance fluorescence
Fernando Quijandría, Ingrid Strandberg, Göran Johansson
In this work we demonstrate numerically that the nonlinearity provided by a continuously driven two-level system (TLS) allows for the generation of Wigner-negative states of the el…
