Description
We investigate intrinsic quantum correlations—such as polarization and quadrature entanglement—in the ultraviolet dual-comb output generated from a Cr:ZnS-based system operating at 2.4 μm. Using nonlinear crystals such as periodically poled lithium niobate (PPLN), we have coherently interfered harmonics up to the 7th order (330–390 nm) with sub-femtosecond timing precision and observed stable mode-resolved spectra exceeding 10⁶ lines and resolving power (λ/Δλ) above 10⁷. In this study, we evaluate quadrature entanglement and quantum Fisher information from our archived dual-comb interferograms, assess the presence of quantum correlations, and explore implications for UV metrology and the future development of a nuclear clock.
