Multidimensional four-wave mixing signals detected by quantum squeezed light

2021 · Proceedings of the National Academy of Sciences

Four-wave mixing (FWM) of optical fields has been extensively used in quantum information processing, sensing, and memories. It also forms a basis for nonlinear spectroscopies such as transient grating, stimulated Raman, and photon echo where …

Experimental measurement of quadrature squeezing in quadripartite entanglement

2023 · Optics Letters

Multipartite entanglement is one of the most fundamental and important resources for quantum information processing in both discrete variable and continuous variable (CV) regimes. For its applications in the CV regime, such as the realization …
