- Abstract: The interference pattern in electron double-slit diffraction is a hallmark of
quantum mechanics. A long standing question for stochastic electrodynamics
(SED) is whether or not it is capable of reproducing such effects, as
interference is a manifestation of quantum coherence. In this study, we use
excited harmonic oscillators to directly test this quantum feature in SED. We
use two counter-propagating dichromatic laser pulses to promote a ground-state
harmonic oscillator to a squeezed Schr\"{o}dinger cat state. Upon recombination
of the two well-separated wavepackets, an interference pattern emerges in the
quantum probability distribution but is absent in the SED probability
distribution. We thus give a counterexample that rejects SED as a valid
alternative to quantum mechanics.

Inhomogeneous oscillation suppression state (or the oscillation death state) does not occur in the classical limit.
In the deep quantum regime we discover an oscillation death-like state which is manifested in the phase space through the symmetry-breaking bifurcation of Wigner function.
Our results hint towards the possibility of the transition from quantum amplitude death to oscillation death state through the "quantum" Turing-type bifurcation.
