A heralded programmable source generates tunable non-Gaussian quantum states and temporal waveforms by engineering the heralding arm, demonstrated for single-photon, cat, and two-photon states.
Experimental observation that light from a driven dense ensemble of two-level atoms exhibits non-Gaussian statistics due to higher-order atomic correlations without first-order coherence.
For generalized coherent states, the normalized intensity-field correlation deviating from unity is a sufficient nonclassicality witness, with a closed form for Kerr states.
The maximum heralding probability for generating nonclassical states from two-mode Gaussian states via photon counting is derived analytically and scales polynomially with the number of detected photons n.
Engineered non-Gaussian coherence serves as a thermodynamic resource that optimizes quantum battery performance beyond Gaussian states for Gaussian charger profiles under unitary dynamics.
