This research advances quantum optics by characterizing third-order squeezing in degenerate three-photon systems, revealing a single stable state that contradicts earlier predictions for similar driven systems. By employing positive Wigner functions to bypass analytical limitations of conventional methods, the study provides refined tools for analyzing non-Gaussian quantum states essential for future quantum information processing.

Researchers Characterise Squeezed Light from Three Photons

Unlike comparable driven systems prone to multiple stability points, this degenerate three-photon conversion exhibits single stability across most parameters. Characterising third-order squeezing within the cavity revealed limited regions supporting only one stable light state instead of several predicted by earlier models. This advance necessitated employing a positive Wigner function, a technique bypassed when standard analytical methods failed due to complex higher-order derivatives.

Characterising non-Gaussian quantum states remains an ongoing challenge in areas such as quantum information processing and computation. Methods for analysing these complex systems now develop through investigating degenerate three-photon parametric down-conversion within an optical cavity. The system exhibits only single stability across its parameters; unlike other driven dissipative systems which typically show multiple stable configurations. Researchers have clarified the behaviour within complex light interactions involving multiple photons, revealing an…
